In this case a security person appears to have used their position to change chrome for google users to display a message when they visited a website of a contractor google was working with (that was anti-union, the employee presumably being pro-union).

This sounds like a stunt someone who hadn't gone to college yet might pull, but this person was a google engineer in a position of trust / authority - not sure how the google hiring process works but she made it in.

I mean, no business is going to willing let one employee hijack the browser used by their users to spread a message the company doesn't like. Most businesses make this very clear - you can't use company resource to spread your messages (political, MLM, side hustles, religious etc).
