Maybe you want to play/watch the thousands of Flash games/animations that exist? Use legacy software that depends on Flash?

I agree that it's an insecure piece of crap that shouldn't be used in any modern system, but that doesn't mean that everyone should be restricted from trying to use old software that depends on it, as long as they asume the security risks of doing so.

There’s a lot of original content (animations and games mostly) that only lives in .swf format. It would be nice to keep flash around if just for archival purposes.

Same reason we have SNES emulators, or the MiSTer fpga project

Strong Bad. Probably Badger Badger Badger and some games, but mostly Strong Bad.

Strong Bad lives on YouTube now. https://www.youtube.com/user/homestarrunnerdotcom/featured

There's no interactive elements on YouTube though. I'm sure 99% of viewers don't really care, but it's not entirely the same.

Besides all the interactivity being gone, they never bothered to upload large chunks of the backlog.

It's more about the precedent set by the ease with which large companies can issue takedowns like this. Eliminating that ability is the issue at hand.
