Bethesda had absolutely nothing to do with “ruining skyrim mods”. Bethesda built the game for Windows, not Linux, it’s not their fault the game has issues running mods on a platform it wasn’t intended to run on. This is like saying “fuck toyota” because your gasoline car won’t run on diesel.
As an aside, you absolutely can mod Skyrim on Linux, with USSEP and SKSE. With one quick google search I found multiple guides.
