Your initial premise was that APPLE was Profiteering from Adapter-sales. When I show you that that didn't HAVE to be the case, you PIVOT to say instead:
1. Well, it doesn't matter if you buy from Apple or not.
2. You wouldn't want "cheap dongles and cables".
3. A crippled USB 3.0 Port is still better than using a tiny $2.50 (3 pack for $7) USB-C to USB-A adapter like the one below from Amazon that you can just snap onto the end of your precious USB-A thingy and forget it. As I said, you can easily turn a single USB-C port into a USB-A port (or four) (and many others) at any time; but you can NEVER turn a USB-A port into ANYTHING else. It is a USB-A port, and that is that. Meanwhile, each USB-C port can be up FOUR Full-Bandwidth USB 3.0 ports (not a Hub, but rather, a breakout) for $10. So, either way, you have MORE choice, not less, with USB-C.
End of discussion.
So, it’s patently obvious that ANYTHING I say will simply be gainsay-ed by you, as you keep moving the goalposts in a desperate attempt to find something objectionable.
By screaming at these people for so long, you’ve managed only to muddy the issue. The complainers’ primary gripe is that they don’t want to buy an ultra-thin, ultra-light, ultra-simplified laptop and then hang a bunch of dongles off of it just to regain important functionality the previous models offered for less money without dongles. We all know that Thunderbolt 3 is superior to every port which came before it. That’s beside the point. Thunderbolt 3 is hard to love when you don’t own any Thunderbolt 3 devices. All it promises for the time being is dongles now, rewards later, while destroying the elegance of the MacBook Pro.
