That's just fine. I do not argue for the quality of Flash, just the option for each owner of hardware to use it if they wish to do so. If the option existed, you could hate that "pig" all you want and not use that option. But I could use that option and deal with the poor quality of that "pig". At least I could still get to use features that are otherwise locked out.
More simply, in my own case, I don't care so much about the quality of some video, but there is certain functionality (particularly interactive elearning only available via Flash) that matters. If that skips some video playback frames, it doesn't really effect the quality of the e-learning experience. However, if it is locked out- because Apple- or YOU- don't like it, it's impossible for someone like me to even have the experience at all.
There are hundreds (thousands?) of apps in the app store that I could call "pigs" too. But I don't make a case that they should be removed because I personally don't like them. Perhaps you do like them, and good for you to be able to access and use them. This is not really different from that.
