My understanding is that the protests were closely coordinated with lawyers, and Google will likely spend a ton of $$$ defending the terminations as a result.
The case law is really clear here, unless the Supreme court has gotten progressive enough to overturn their 1939 decision (which is really not possible), this will not make it far at all in court (anyone can sue anyone for anything, but this probably gets thrown out before pretrial). If they got advice from lawyers, however, that this was ok, there is probably clear grounds for a legal malpractice lawsuit.
I really doubt Google is going to spend much on this at all.
I think you've been misinformed, but this is the internet, so anything goes really. I can't imagine any lawyer, or anyone who can use google to search for things, thinking they can get a decent payday from this.
