Sorry, that makes no sense to me. First of all, nobody is unbiased. Most of the people posting on this forum are either somewhat biased for or against Tesla, no news there - it is a result of plenty of TSLA investors (bias for Tesla) and Tesla car owners posting negative practical experiences as the likelihood of posting negative experiences is higher (you have a problem, you post it, hence a resulting bias against Tesla on the experiences forums). In between these is a positive bias generated by Tesla fandom, which certainly exists.
Second, on a forum such as the Model 3 forum - or pre-release Model X forum before it, or Model S back in the olden days - limited data and context is part and parcel of the stage at which the product is in. Tesla the company is not sharing with us anything that is not in their interest, yet the buyers, active investors (longs often are not) and other interested parties have an interest in knowing more than the company is sharing. Finding out is, by nature, limited and incomplete - rumors, leaks, speculation.
Leaks - even those very true leaks - are nearly always incomplete data, partly to protect the source of the leak or the person posting the leak (e.g. new anonymous account and details omitted), partly because the information itself gathered and available through this method is often incomplete. That doesn't mean it can't be valuable or accurate, it is just partial...
It is a game, really. The company putting on the best face they can, for their own interests, and on the other end other parties trying to see beyond that face and find out reality, for their own interests.
p.s. I'm sure there are also the occasional short still, though I would guess the number of those has actually gone down over the years, TMC just does not matter for that as much these days. But it remains exactly the kind of place where someone who has learned something from a friend, would go to post. Hence I find the news in this thread plausible. It may also be false, of course.
