That is not true unfortunately. I tend to be very left wing socially - economically I’m more left of center - and that was reflected on my social media as well - either pushing me towards more radical content or stoking anger with more radical right wing content to get me riled up and coming back for more.
I ended up with a growing hatred and emnity for a growing number of people and “groups”, and black and white thinking. Even though I was aware that I was being manipulated, it was still impossible to sit on a high horse above the fray.
It’s quite easy to manipulate human minds, even ones that are careful and aware. We can all be manipulated. It’s why advertising works, for example.
The only thing to do really is to not play that game. Avoid advertising, avoid other content curators deciding what you get to see and telling you how to reason, etc… realise that most people are empathetic, that most people want what’s best, and those that are radical have been manipulated to be that way, sadly.
Your iPhone / Samsung is manufactured there. So no, that’s a bad take. You get what you pay for, and good quality is still cheaper than made elsewhere.
