There are two spots where #Google, #Amazon, #Facebook, #Apple, #Microsoft (and others) are most vulnerable. You have to attack them where it hurts them the most.
1) Is their public image. Make them look as shitty as possible, they deserve it. Ideally, make them *deny* things that make them look good. This is the high art of pissing someone off. Claim publicly that Google is stopping AI research or whatever. You will win.
2) Don't use their services. Seriously. Stop. Stop. STOP. Delete. Forget.
