At that point it wasn't as much about control[0] but as that the runtime really was bad. I used it when they released Flash on Android and it was completely unusable. Extremely laggy, the mouse events did not map to touch events well at all, and it would out of memory crash all the time.
Replacing flash on the web with HTML5 was actually a good thing. It's just unfortunate that nobody has built any good web authoring tools for "mere mortals" to use.
[0]Remember the iPhone was launched with no App Store, and Steve Jobs just thought that everyone should write PWAs in HTML5. It took developers jailbreaking the phone, making native apps, and massive internal pressure from Apple people to make him go ahead with the store. But it was partially about control because at the time Flash was a huge source of security bugs and drive-by virus infections from just loading a flash ad. Apple would have to release emergency OS updates if they had bundled flash and they never wanted to be tied to someone else's schedule.
