I just recently found that Vimeo is hosting MST3K, with free playback of the original episodes (Joel and Mike).
So for selfish reasons this makes me sad. I'm guessing MST3K will need to find another host, perhaps with less generous terms.
Edit: I really hope that doesn't mean RiffTrax will also have problems.
They are also the backend for Dropout, which has just shy of 1m paid subscribers.
So I understand your selfish sadness feelings.
Hmmm... I just learned that mst3k has even more moving parts at the moment: https://www.byteseu.com/1717645/
