was probably astroturfing from corporations

Could be. At least when I still was on r/linux a few years ago there were about three usual suspects who would pop up every time a topic even went in the general direction of licensing and spewed their toxicity. To me these people had less of a corporate shill vibe and more of a undiagnosed mental health issues vibe, but I obviously can’t say for sure.

There is the x32 ABI that tried to have that 64bit cake and eat it too, but it didn’t catch on, probably for good reasons. Gentoo still allows you to run it on modern hardware in case you want to try it out.
