Its just what we are used to.
As a lawyer, all the people you named, all politicians, all celebrities, and especially all media outlets, both traditional or not, are not "the source" of any information. Let me put it another way, with what I am used to, its only a minimal amount of diligence to get to the actual source.
Today for example, the US Supreme Court issued two rulings on Circular 230 cases, dealing with Google's liability. Since I can easily get the actual ruling, i know that any "report" of today's cases is someone who read the ruling. In the case of Twitter its a tweet of someone who may have read what someone wrote about the ruling. And then, with Twitter, its what someone thought about what someone wrote about what someone else wrote about the ruling.
Twitter easily gets you like five levels removed from the actual source!!. And to no benefit. Read the actual source.
Anyway, that's why I am not on Twitter, and other people are. It would never occur to me that the people you named above are the source of anything, even a piece of legislation drafted supposedly by a member of congress is actually drafted by staff, its a fair bet that most congress people don't even read what they are voting on. Why would I care about their summary?
That's the crux of the difference of opinion. As an investor, I care very much about actions Elon takes with respect to Tesla. I care quite a bit less about 30% of the stuff he says is going to happen at Tesla, as he has a record of being overly optimistic. I don't care at all about Elon's opinion of the crime/homeless situation in San Francisco. I mean, were are not pals. He doesn't even live in San Francisco. If I want to find out how San Francisco is doing, I can, like go there, or I can find many sources which are not celebrities or politicians to see what data there is.
But he clearly loves the fact that people read his tweets about crime in SF. He loves it so much he bought the whole company!
The TMC "investor's roundtable" is by far the best source on the company. By far. It consists of people who consistantly post links to direct sourcing of data. Sometimes its posts on other opinions, but the value is really that the TMC posters care enough to do some research prior to posting. On that forum you had guys tracking shipments of Teslas on RORO ships docking in Europe!! With the dates the ships left port and GPS coordinates!
The TMC Energy products forum has actual licensed electricians posting on the technical requirements of systems!
Twitter is just too far removed from the actual sourcing for me. Obviously, reasonable people can differ on this. That much I have learned here.
