Has nothing to do with Flash ads, it's just that I keep activeX disabled until I come across a site where I really need it (like online virus scans), and IE or the IE shell I use, can't load flash without it.
But regarding all-flash sites, those I refuse to use. I use mouse gestures for most everything, and they don't work in Flash. Neither do most of the 8 buttons on my mouse. The back button does nothing, forward, etc. You can't copy text and it takes too long to load. Beyond that, no matter WHAT they tell you, adopey is downloading something other than the flash player when you DL that. I saw a yahoo something or other even though I had unchecked it before DLing.
I just despise flash as a technology. It's not HTML/CSS, it doesn't run in your browser. It obeys none of the rules of a webpage.
There is nothing to fear, but life itself.
