Issues with accessing financial data seems to be a region specific problem, Where I live there are numerous services which offer such data + analysts view of the company's performance and if not it's accessible through govt. website since it's a public company. So if you mention your region, I'll ask the moderator to update the problem statement with it.

As for social media for stock market investment/trading, The main issue is people trying to game each other i.e. If one wants to sell, They'll tell others that they're buying; This is rampant in any stock market information website which has built-in social forum. E.g. Look at forum section of this highly rated stock information website in India - https://www.moneycontrol.com/india/stockpricequote/pharmaceuticals/drreddyslaboratories/DRL ; It's either people trying to game each other (or) outright spam trying to advertise their services. If you want high quality discourse, Then you need extraordinary moderation in place which is difficult to keep up with with high phase of stock market and so you need to solve these problems first.
