I still think this is way off-topic and not related to Tantacrul or his content (and rather, his employer). But why are you blaming Muse Group for everything and not the Audacity devs?
Wouldn't they be the black mark of the FOSS community for accepting money from a known bad entity? I also think this is discounting a big problem in the FOSS community, volunteers giving years of their free time on passion projects while dealing with angry users and not getting one cent out of it.
I routinely see people bitching about OBS and its devs for not being utterly perfect for their setup because they forget that once upon a time XSplit used to be the only good option. How much have they paid for OBS? zero. If company X comes and says "hey I can actually give you a living wage to work on your passion project" I think it's in some case reasonable to see their loyalty to whiny end users to be quite fragile.
