My starting position is that he is guided by business pressures not terribly different from YouTube's, from the following anecdata:

I understand Linus started Floatplane because his business relies on YouTube, a single point of failure

With PIA/Kape, he left whether or not to accept advertising dollars up to a user vote in YouTube's chat. It came out tied at first, and then he went to the Floatplane stream to break the tie, which ended in favor of accepting PIA advertising

In live streams he has spoken somewhat negatively about "free speech" advocates

I think Floatplane will simply go where the dollars go in the long run, and I see little in the way of moral conviction that they would e.g. fight government regulations or payment processor demands.
