I am quite skeptical that an acquisition by Nvidia will make people move somewhere else ... The network effect remains central, if you are researcher/lab/company and you want to promote your model/dataset you go to the popular platform where most of the community is. The same way most of the public repo are still being published on GitHub despite people being pissed of by Microsoft acquisition. (I you add on top of that the cost changing your workflow, not using HF library, ... it make the transition even more difficult)
