Am I overreacting by seriously considering starting the process of migrating from gmail? It's not this singular incident of course, but just the continued pattern of behavior from Google for the last couple years. I really have lost all faith in them respecting their users.
These days I host my own anyway, and have a blargh@host mail account I use to sign up for things (typically blargh+thewebstie@host so I can track who is selling email addresses)
