No one told anyone to run out and get anything, once u realize that then maybe you will stop complaining.
Where does it say you have to buy MagSafe?

MagSafe Charger Only Charges at Full 15W Speeds With Apple's 20W Power Adapter [Updated]

You are the liar.
Is there anything positive about this product?
USB Power Delivery profiles, basically. A device’s bundled/intended adapter (Apple’s 20W one) might support a particular profile’s characteristics to do 15W output, but another adapter of greater maximum output might support a different combination of profiles. IIRC, use iOS’s magnifier to take a snap of the fine print on Apple’s 87 or 96W adapters and you should find it doesn’t support the exact one that delivers 15W. When a charger doesn’t support the exact profile a device wants to use, it’ll step down to the nearest profile it does support, which will be the 10W one in MagSafe’s case.
I have Apple's new 20 watt charger. And with the included USB-C to Lightning cable that came with my 12 Pro, charging is very fast.
For $20, that charger is a good deal. And with all of its regulatory approvals, there's no way I'd consider another brand. And...it's volume is slightly less than the 12 watt charger that came with my iPads. Good job Apple!

Disappointing. Wish I knew before I bought 2.
"...that seems to be one of the the only charging options..."
It's either "one of" or it's "the only." Is it one of the few options? Is it the only option?

This is what happens when manufacturers use non-standard wattages. The USB-C spec was designed with these profiles in mind:
- Profile 1 : 5V@2A
- Profile 2 : 5V@2A or 12V@1.5A
- Profile 3 : 5V@2A or 12V@3A
- Profile 4 : 5V@2A or 12V@3A or 20V@3A
- Profile 5 : 5V@2A or 12V@5A or 20V@5A
Go green, aka how to turn 2.2bn fully working USB-A adapters Apple sold with iPhones into useless trash.
interesting, now can we get fixit to do a teardown and comparison of different chargers?
Apple is unfortunately not truly forthcoming with the MagSafe puck, they should state that 15W charging is only possible with a specific charger. I am hoping that it is not something Apple proprietary but USBC PD that other chargers could do too ...

Good thing everyone has a drawer full of those already!
Oh wait.
Oh wait.

It's really curious though. My understanding is that while the PD spec strictly enforces the voltage, the current can vary, thus allowing power to vary (which is often necessary when trying to regulate power to a Lithium battery to prevent damage).
Assuming the Magsafe adapter needs 20W to charge the iPhone 12 at 15W (~5W going to inefficiencies due to inductive charging), it would seem like a 12V should be more than sufficient.
Does anyone have a photo of the PD profiles the new 20W charger supports? Hmmm...
Ah... maybe this is the answer. It looks like a 12V USB-C PD profile is needed to support 15W charging?
on one hand, this is kind of irritating that you need the 20 W adapter to get the full 15 W for magsafe.
But, I’m pretty sure that the 18 W will work just fine. The video said that it got up to 13 W, and the difference between 13 W and 15 W is extremely minor.
Plus, I plan to order 2 HomePod Minis, which come with 20 W adapters. If the HPM works just fine with an 18 W adapter, I’ll just swap one of them out, and use the 20 W that came with the HomePod for MagSafe. hopefully Apple doesn’t put any stupid restrictions when using an 18 W adapter with the HomePod mini. That would just be ridiculous

- Apple could make the packaging smaller so they could ship more. (Saving Apple money)
- It might save the environment in the long run but I think a USB-A cable would have been better as people have a lot more USB-A bricks than C.
(Saves Apple money and is a cash grab for the 20 watt brick and MagSafe)
- MagSafe, overprice money grab.
(Overpriced money grab)
- $39 MagSafe cable still requires a $20 power adapter.
(Overpriced money grab)
And you probably thought I was going to counter your points.
AirPower would not have been any better. First of all, according to Prosser, AirPower would’ve started around $249. It probably wouldn’t have included any adapter, and you would probably need at least a 30 W to charge all three devices at once at a relatively fast speed.
I don’t know what the heck is going on with Apple. I can’t remember so many gaffs during their product releases. First, the deceptive pricing. Then the puck’s (and the wallet’s) poor adhesion. Then the marks left on their cases (which now they’re saying you shouldn’t use when charging). The fact that they’re telling customers to use their old chargers when they’re shipping a different cable with the phones. Now this. And there are still two more phones to be released. Let’s see if Apple can keep its streak going.
Nevermind, I found it.
So it runs 20W at 9V/2.22A. So that's the key thing - if the power adapter doesn't support 9V at that current, it's not going to be able to properly power the Magsafe 15W charger.

Its laughable that anyone actually thought it was about saving the planet and not about profits.
With my xs max and a a zens QI charger “optimized” for apple i see that for short period of time it can go 12+W but quickly come down. (Please note that battery of the phone was not full empty)
so to me the whole story of fast wireless charging is a lie, as only for x minutes maybe it reach that power and then due to heat and optimization all goes slow...
