> Whataboutism or whataboutery (as in "what about…?") is a variant of the tu quoque logical fallacy, which attempts to discredit an opponent's position by charging hypocrisy without directly refuting or disproving the argument.

Let's look at your post again:

> Really? What does Google deserve when it nags me about switching to chrome whenever I use any of their pages from a browser that's not chrome?

If that isn't whataboutism, then you really ought to work on better phrasing your thoughts.
