And exactly why would I care, what uninformed people at companies and what uninformed politicians do? And what does that have to do with me being in an "echo hall" (I think you mean echo chamber, btw..)? In what way is whatever platform politicians use indicative of that platform not being an echo chamber?
It doesn't matter whether you care or not. Your personal opinion is of no importance when it comes to mass-market social media and other horizontal platforms. The point is that a lot of politicians and business leaders will continue using X regardless of what you think of it.
You still didn't answer the question though. I asked you why it matters, whether politicians make uninformed use of a bad platform, when it comes to me being in an echo chamber or not. I think there is no relation between what silly things politicians do, and whether I am in an echo chamber or not.
I am not sure why I wrote "echo hall". I must have been mentally absent or something. To my own ears it sounds weird and not like something I would usually write. It might have been weird auto correction on phone. I am not sure. Anyway, that is besides the point. I would like to know, why you think, that what politicians do has any relation to me being in an echo chamber or not. I mean, do you define the outside of echo chambers to be the place, where politicians go? Like ... Are they such a massive number of people or somehow indicative of that outside? I just don't get your idea.
If you are only getting your perspective from tertiary sources rather than primary sources, then you are more likely subject to a bias layer from intermediaries.
I really dont think I am saying anything controversial.
