I don't think treating websites or webmasters badly is the only reason; there is banning in Fecebook too, and they don't are serious for their users interests as well. All of them, Google, Facebook, Bing, Twitter just do what is in their interest and 'in their whim' (this one is too unfortunate). They least care about for usability and for comfort of their end users. Real reason for downfall of G is the social things happening so much, that shaking everything in the search world as well. They need to think seriously stepping into social networking and social sharing area.
..there will be a complete reversal in how they treat webmasters. If it doesn't happen, then we'll add a footnote to Wikipedia about how arrogance of the PhD was their G's ultimate downfall. :)
