I think people care because Twitter, in conjunction with the government, has silenced and booted off people with opinions that don't fit the approved narrative.
People have been kicked off the platform for "spreading misinformation" when the information turned out to later be true. This is what Elon Musk says he wants to fix.
And I'm not talking about Trump or other Republicans. I'm referring to doctors who dared to say anything about vaccine side effects or to question their efficacy; the sort of conversations that should be a legitimate and open-forum debate on an unbiased platform.
