Funny you mention Paint.Net. Two years ago, I made a very similar comment on the Paint.Net forums about misleading ads as download links. The ad in question was a link for downloading GIMP (bundled with crapware). The support forum volunteers just made fun of me and called me idiot names. Rick Brewster politely explained that he didn't want to lose money on ad revenue and needed the ads positioned very prominently. Search for (in quotes) "Ads on the website" to see the beating I took. So I have to applaud GIMP for taking a stand.
