You're right, Google controls what I see and pushes right wing propaganda to my phone. TikTok's algorithm actually works to serve me content based on my interests, and I have true political discussion and discourse there.
Android will push notifications for news articles that you may be "interested" in. I think it used to be called Google Now.
Congress is concerned about theoretical propaganda, but it's a reality in nearly every major news outlet and tech companies, but zero concern when it fits a certain narrative.
Huh. Curious. I've been using Google Now, and after that, its successor, for a long time. Rarely do I see any political propaganda. Just sane reporting. I'm based on Northern Europe though.
I hope you mean Google, they track you all over the web whether you want to be tracked or not just because lazy web developers can't be bothered to host their own fonts (and other ways but that's just one example). You have to deliberately download or use TikTok for them to get your data.
