Picking the two extremes does not prove your point. A lot of people are pissed with ads right now. Imagine if they would have to pay for them too (even pennies).
Not when the ads come from different domains (which is the case for 99% of the annoying flash ads). Adblock stops all requests to these domains. Incidentally, this is also why Adblock is a hit with privacy-conscious people - it mitigates tracking through log file analysis.
no. picture and flash ads are separate HTTP requests. AdBlock/FlashBlock work by not making those requests. You will save bandwidth, but as you have pointed out, it's a drop in the ocean compared to watching a HD movie or even a 10min youtube clip.
