We have a vastly different software culture today. Constant churning change is superior to all else. I can't go two weeks without a mobile app forcing me to upgrade it so that it will keep operating. My Kubuntu 24.04 LTS box somehow has a constant stream of updates even though I've double-checked I'm on the LTS apt repos. Rolling-release distros are an actual thing people use intentionally (we used to call that the unstable branch).
I could speculate on specifics but I'm not a software developer so I don't see exactly what's going on with these teams. But software didn't used to be made or used this way. It felt like there were more adults in the room who would avoid making decisions that would clearly lead to problems. I think the values have changed to accept or ignore those problems. (I don't want to jump to the conclusion that "they're too ignorant to even know what potential problems exist", but it's a real possibility)
