One of those is considered a custom order though - meaning Apple does not stock laptops with two separate chargers in stores. You have to order it and wait for it to ship out from China.
If so, that's just lazy logistics/bad packaging design on Apple's part - plus it's
already the case (nothing to do with EU) if you want a discounted 96W charger rather than the minimum 70W charger with your MBP.
It's not like they have to build the Mac specially (if you order a MacBook with 16GB RAM and 8TB SSD then
perhaps), just pop a box containing Charger A or Charger B in the top of the packing box. I can go to Amazon, order a box of tea bags, a USB-C dongle and a dog toy for a total of less than £10 & they can contrive to put them all together in a box and send it next day, in return for a very slim profit margin. Apple are selling premium, high-value items with a huge profit margin, yet (esp. under Cook) they pare every possible penny off their logistics costs, at detriment to the customer. That's on Apple, not the EU.
That said, I can also just see the logic of them reducing the price by 100 eros (which they did in the EU) and not including a charger. Done and done.
Except, in the UK, they didn't reduce the price, and still removed the charger... and Apple's "generosity" in the EU price could just be because the euro has risen against the dollar - i.e. the "price cut" was probably coming anyway.
Although it seems that most other manufacturers are also ditching the charger in the EU, many - such as Microsoft - even before Apple.
Apple dropped the bundled charger from the iPhone long before the EU required it.
Thing is, though, EU regardless, now there is a genuine
choice of chargers for MacBooks (basic, fast-charge, multi-port, TB dock & reliable 3rd party options) unbundling the basic charger makes perfect sense - and that's been coming since Apple started switching to USB-C charging on Macs years ago.
Pricing is a little different topic, but of course related. You're right that the EU doesn't say anything about pricing (I believe)--and it's because they can't. As far as I'm aware, governments can't dictate how companies price these kinds of consumer products.
As it should be - and the common charger directive should increase choice and competition. Apple are already offering Anker and Belkin chargers in their online store, and sensible people who need a charger with their Mac aren't going to spend £60 on an Apple charger if they can get a reputable 3rd party one for £40 - which is good news if you need an extra/replacement one.
First, there is what the charger is worth to the customer, and then there is what the charger is worth to Apple--two very different numbers.
...but only one is relevant to the customer, and that's how competitive markets are supposed to work. It's up to the customer to say, "hey, no, if you're not giving me the charger for free I'm not paying £60 for an Apple trickle-charger when I can get a (reputable party) fast charger for £40"
Apple sell high-value goods with substantial profit margins, and Macs are almost certainly priced based on arbitrary "what the market will bear" price points which bear little relationship to the marginal cost... Hence the dollar price of a base iMac not having changed from $1299 since
1998. Offering a free or heavily discounted charger with a £1600 MBP is well within their zone of negotiation.
A voucher for a free charger is an alternative to a discount and potentially the fairest option. Unfortunately, the problem with that is I think 99.9% of people will redeem the free charger just to not lose out on the value, which will defeat the EU's purpose for the law--so in my opinion that will probably be a no go.
Apple love to talk the talk on the environment - if they wanted to walk the walk they'd offer an incentive to leave the charger rather than use it as an opportunity for a stealth price rise (as in the UK).
"Free basic charger or a £
x Apple Store credit" would seem like a good deal, where
x is calculated to make a net profit by encouraging people to spend additional money in the Apple Store. I'd take the credit and use it against a high-end multiport charger, they'd still take a profit.
Apple are allowed to maximise their profits by pinching pennies, but customers don't have to take that lying down.
