I hate it as much as the next guy, but I certainly don't see why it should be illegal (and disclaimer
Debian on all my personal machines, macOS for work).
Should it be illegal for books to have a list of similar material from the author/publisher? Should food staples not be able to list recipes on the back?
I completely agree that pulling the rug out from under the customer should be illegal (i.e., effectively changing the terms of service for an already-purchased product), but having a shitty product shouldn't be illegal IMHO.
Yeah I think we're in violent agreement to an extent
as I said in my last graf, if it's effectively changing the user agreement, absolutely not ok. But if it's a shitty product to begin with, then I'm just not going to buy it in the first place.
So yeah, Windows doing shitty things for users who have already paid for the product is definitely not cool. But for all users going forward to have a shitty experience? That's... shitty, yeah, but I personally don't think it should be illegal?
