If you're a game maker and you only sell your game through steam, you are at the mercy of a company that does not have your best interest in it's core mission and will almost certainly fuck you over at some point, and you're missing a large audience that does not buy from steam.
What's the best path forward? I dunno! Too much work, but that's the hand we've been dealt.
