If you don't want to read sites without some commercial interests, start by never coming here, since this site has ads too. I'm not sure where you could find a *.com site without commercial interests--that's what *.com sites are after all.
I saw no ads in that blog -- that was not an issue. The issue was misrepresentation. The blog sounded like a JAMS-sponsored opinion with no backup info provided, and you quoted that opinion as a fact.
