About ten years ago Adobe made a strategic decision to kill Flash.
They stopped working on ActionScript tools (Flash IDE, AS3 compiler, etc) and switched all their web designer tooling (web animations etc) to Javascript. For a while they kept pushing out Flash security updates, but only because they had an enormous existing install base - but even so, that happened with a skeleton crew, and I'm not sure it's still being maintained.
So yeah, there's nothing stopping them now - because they already stopped years ago.
