eli5: Why is Flash Player a dying/dead program, is it just obsolete?

Pretty much, yeah. When Flash came out, it got popular because there was nothing like it. But Flash is not very secure, even back then. Nowadays, there are simply more, better and safer alternatives, like HTML.  
  
EDIT: It's worth noting that this isn't a sudden kill on Flash. Websites have been slowly fasing out of Flash after being dependent on it for so many years. Like how in 2016 (IIRC), Google no longer supported Flash Player as a default feature on Chrome.
