I'm never going to go on strike to protect the rights of bizarre anti-border extremists to harass and stalk their colleagues instead of working. I'm pretty sure that 99% of all developers are just like me. Why would we not side with management here? Google's management has to be the tamest, most worker friendly management in the history of management. It's the very last place where workers need to unionise.
I remember Google a long time ago, nearly 15 years ago now. There was an April 1st when someone managed to find a way to send email anonymously to all of engineering, and sent round a call for unionisation as a joke. We found it quite amusing. The idea that Googlers would unionise wasn't just seen as unserious but literally, an idea worthy of being an April Fools.
