Flash continues to suck (possibly)

A Flash developer on the subject of touchscreens:

The only potential “solutions” to the mouseover problem are terrible ones:

A) The best case: every Flash app on every site is re-thought by its designers and re-coded by its programmers (if they're even still available), just for touchscreens.

Really? Are you seriously telling me that every Flash application out there is entirely dependent on being able to point the mouse at things without clicking?

Even if you ignore touch screens, that still violates WCAG 2.0 2.1 by being inaccessible to keyboards.

I have trouble believing that every single Flash developer is that bad.
