Okay my bad, I think I just misunderstand BSD-3 and read somewhere that Proton is Valve’s proprietary software. In terms of open source software, the only licenses I’m really familiar with are GNU, Apache, and MIT. So I read one thing online saying Proton was proprietary and assumed BSD-3 was a proprietary license without looking into it further.
