You can ask legitimate questions about Amazon's treatment of employees. Boycott them if you're so inclined. Are they being paid fairly? Are they being exploited and over-worked? I think it's a conversation worth having. At least be sensible and call for regulations that address this in particular, not trying to break up Amazon entirely.
Google is guilty of what, exactly? Do you dislike how they treat you, the user, as the product? Change your Google privacy settings or better yet switch to Google alternatives (Protonmail, DuckDuckGo, Microsoft Office, OpenOffice, the like, YouTube is too useful to abandon).
All I see is a big push to vilify tech companies so politicians can look like they're for the little guy.
Take the recent Google internal vulnerability case. All of the sudden politicians come out of the woodwork, when public disclosure of this sort of thing was never an issue before. In reality, people doesn't seem to understand that enforced disclosure of internally discovered vulnerabilities will make more proactive actors look less secure than companies which aren't as rigorous (and have less to disclose).
If you very understandably don't trust Facebook with your data, simply get off it. Use Signal, SMS, email, Discord, Slack, anything else you want to talk to your friends and family.
I suppose telling people not to use Facebook, Instagram, or Google services doesn't have the same ring to it as tearing companies down though.
Edit: Changed nonsensical sentence about Google's vulnerability disclosure. Clarified.
Edit: Reclarified still nonsensical Google vulnerability disclosure paragraph.
Edit: Changed "more" to "less" in the disclosure paragraph. Third time's the charm.
