Is Google trying to mandate use of Adsense on Blogs?

Lots of people are complaining how their Blogger.com blogs are being shut down and one often cited reason is for spam. But, Google doesn't seem to mind if you have no affiliate ads and only use their Adsense to monetize and that's not considered spammy, regardless of how little money you are earning. And, considering how Google owns Blogger, it makes sense if not a little biased to require or expect bloggers to use one specific ad network.
