To avoid contributors from Google is ... a feature? What exactly is your problem with them?
A nonviolent, voluntary and intentional abstention from dealing with google, in order to encourage google to alter an objectionable behavior.
1) Excluding Googlers, which isn't very nice.
2) Applying pressure to de-evil Google, which is very nice and benefits everyone.
I'd like to have a non-evil Google again. I really miss the old non-evil, brilliant Google. Organizations change.
Let’s have them do work as individuals instead of Google employees.
