They sponsor a window manager called Hyprland, which is developed by some aggressively unwoke guy. When dealing with it Framework has blundered, babbling about a big tent instead of publicly asking the guy to stop being an idiot if he wants to keep receiving money.
I suspect people asking to boycot Framework tend to forget that people occasionally need to buy new laptops, and when doing so they have the choice between 1) a repairable laptop developed by a company supporting open source, and 2) a non-repairable laptop lining the pockets of people who are guaranteed to do more evil in the world than whoever develops some fucking Wayland window manager. But this is probably a dangerous take in these parts.
Edit: It seems the Framework also tweeted about Omarchy and some stuff. Not a great look, not sure if it’s boycot worthy either.
