I really don't know the architecture of fmovies but my guess is that it works similarly to sudo-lol but with specific providers instead of a long list of available providers.
Even still, I've wondered how those providers load new content since I've never seen a way for end users to upload new files.
Shows like Last Week Tonight get uploaded almost the same day.
Anyway, to answer your question, I think fmovies is back with their .lol tld though I've moved over to sudo.
There's always going to be a replacement because clearly there's a market for it. If only the people who actually hold the rights would realize that.
