Recently a friend of mine asked me a question: "I just got a message that ADOBE Flash is no longer available free of charge in 2021. Does the Ubuntu system have any equivalent Flash Player so that I can continue to watch videos on Facebook etc?"
[history brain-dump follows] Last time I looked, Google (not Adobe) had 100% responsibility of ongoing maintenance of the browser flash plugin for chrome/chromium, at least on GNU/Linux. Chrome/chromium do not ship with flash built in, but they *do* (did?) download it from google.com into a per-user $HOME area. Assuming the user was allowed to talk to google, of course. Firefox users had a third-party hack to download the chromium blob (from google.com), which IIRC broke at least once due to Google changing what API it used (this was back before firefox went webext). Stand-alone players (inc. AIR) were dropped when Adobe abandoned (linux) flash on Google's doorstep, because Google couldn't monetize that either.
