My problem with flash is the same as with all plugins: scroll doesnt work, mouse-gesture dont work, shortcuts dont work, no control of content. Its like opening an enterly other program in browser without any integration.

Flash did solve the problem that the article complains about: consistency of experience and not having to develop your site / app to a pile of different runtimes.

But that's not a bug, but a feature for those in the business of selling admission to walled gardens. Same as it ever was.
