I don't think the players really care provided it doesn't get in their way more than 5e already does.I'm pretty sure they all like 5E now (the players), plus I don't think they're keen on switching the system on viewers (I doubt many are familiar with how PF 2E works).
Based off watching them actually play it, I don't think they really like the system much at all-- half the group has been playing it for quite a few years now and still aggressively has no idea what they're doing mechanically.
They like Matt's game and the system is lighter weight than Pathfinder 1e which makes it easier for them to muddle through, and works better for streaming, thats about it. Like, Liam might be the only mechanically inclined player at the table.
I also don't think their fans would care, since most of them really aren't watching for the system, at most it would lead some of them to adopt it.
