Watcher are not struggling artists being forced to make a drastic move so they can keep creating. They are people, who don't want to be YouTubers anymore, moving to Vimeo because they believe they can become a "real" TV Studio from there more easily than from YouTube.
They do not care about making content the YT audiences want because they do not want to be YouTubers. They don't care that you prefer the low budget videos, or don't like one series over another, they care about making the TV shows that they want to make. That's all this is.
Watcher went into this fully ready to lose a good portion of their audience because they don't want a YT audience. They only want an audience whos creative vision aligns with theirs - Watcher becoming a TV studio.
This is fine. It's okay to want to pivot your business. The issue is that they decided to attempt this pivot in the most abrupt, insulting way possible - through a video that puts a lot of corporate lip service around making this move "for the fans" while their actions clearly show this has nothing to do with what the fans want. It's disingenuous and condescending.
YouTube audiences not wanting to pay $6 a month for Watcher videos isn't "not wanting to pay artists fairly". Watcher was already being paid (and their apparent mishandling of money in pursuit of projects outside of their budget isn't on the fans). People not wanting to pay them is a direct response to Watcher no longer wanting them as an audience. Very few people want to support a company that takes its audience fans customers for granted, even if they can afford it.
