With Google there is a bait and switch (and it doesn't really just apply to this particular story). They came to market defining themselves as the open alternative to Apple to get market share and developer interest (and evangelism), and now that they've achieved dominance the terms are changing.
There's no surprise that there's going to be massive pushback (and probably antitrust implications).
The reverse is also true: whatever sufficiently good product that doesn't generate money is basically doomed by them no matter how many users depend on it. (Reader, Inbox, Talk, ...)
