Flash had quite a lot of quite severe CVE; how many of those do you suppose are "fake news" connived by conspiracy (paranoid style in politics, much?) as opposed to Flash being a pile of rusted dongs as far as security goes? A lot of software from that era was a pile of rusted dongs, bloat browsers included. Flash was also the first broken website I ever came across, for some restaurant I never ended up going to. If they can't show their menu in text, oh, well.
