I didn’t celebrate per se, but Flash was incredibly insecure and HTML5 was good enough for most games and it came out in… 2008, so 13 years before Flash went EOL.

What I did celebrate was finding out that Ruffle is a thing and most of your old favourite Flash games websites use it now so you can play your old favourites again! It’s also open source and written in Rust so everything necessary to give the programmer nerd in me a boner.
