This is really shitty but it doesn't surprise me at all. He's trying to make a shift because he doesn't want to face repercussions of being labeled transphobic, possibly being widely banned and ostracized.
It's very different when someone actually realizes they were wrong and want to change and be better. Nutomic isn't doing that here, he just wants people to give donations and to avoid fallout from him letting his opinions slip publicly.
I don't know anyone who celebrated except maybe the shitstains at adobe who planted the timebomb in Flash Player. Though that was pretty short lived because people found a way around it, either out or necessity (in china) or because they wanted to keep using the Flash projector to play games on Desktop.
For anyone not aware of the workarounds it was likely pretty shitty for people who needed or want to use software that depends on Flash Player.
Of course now we have ruffle.rs but it still isn't perfect, and there is still software that relies on unimplemented functions. Hopefully those get resolved soon.
