It's the purchases for me. I'd be ok with every user in my domain getting converted into standalone Google accounts.

If they don't do something, I'm going to think about emailing every developer I've ever bought an app from and asking them if they can move my purchase to an alternate GMail account. I'll at least do it for anything expensive that I still use.

I'd love to see a class action lawsuit for Google Play purchases that get usurped.
