I don't think developers have problems with user-enabling technologies (at least I don't). What we do have problems with, however, are technologies that suck away our battery life and CPU time with little or no return, all while bringing a steady stream of exploitable security holes. If Adobe had actually made a serious effort to make Flash a lean, secure machine it'd still be around. Instead, they decided to just keep tacking on new features rather than spending several releases doing heavy optimization and only reactively dealt with security, so here we are. The bottom line is that nobody but Adobe is to blame for the death of Flash.
