If I were a FAANG executive I would be more worried about hiring you not because you have a record but because you would be at high risk of using your job for personal activism.
There’s nothing in OP’s post that says they weren’t extremely careful to leave their views at the workplace door.
A lot of the world is run on plausible deniability. Biden seemed like a great politician for decades. Now he doesn't.
If I was OP's friend, I'd advise to not mention it. If it bites anyway, keep moving. There are far worse things in life than not getting a job at a FAANG.
