Excuse my ignorance, but that this ad blocker block google ads in search results, or rather Flash ads?
I'm asking because, if you push this argument further, you could think that it's good for Google to have all ads served by competitors disappear, to leave only google ads everywhere.
I haven't used privoxy in a while because I don't want to globally block ads and I want to have site-wide filtering system which is easier in extensions and a bit of a work with privoxy. There are supposedly better alternative to privoxy someone once mentioned, I can't remember it.
The thing with privoxy and most other good ad blocking extensions/software is that you can edit the filter list to block almost everything you could possibly think of. So no matter whatever your argument is Google can not stop you from blocking whatever ads you want to block, regardless of the operating system you use (yes even Google Chrome OS, which is a debain/ubuntu based system. Emphasis on Ubuntu because Canonical/Ubuntu developers actively worked on it prior to the official Chrome OS announcement. Not to mention Chrome OS is opensource and you can rip it apart and do whatever you want to do with it).
They could make life a lot harder for AdBlock plugins if they wanted to, but site usability would take a hit and it would always be a cat and mouse game.
