The premise (that "powerful models" implicate "safety" concerns that must be controlled by "companies") does not seem true or self-evident to me. This tired fearmongering campaign centered on GPT-4 three years ago, a model now surpassed by open models that run on laptops.
Did fearmongers like Amodei say, "Oops, we were wrong! It wasn't that dangerous after all"? No. Of course they didn't.
1) the company has device-level control to the degree that they can not only restrict which API endpoints people can connect to but which accounts they use to do so (in which case this already isn't an issue); or
2) they don't, and all bets are off anyway, open weights or not.
