Yes, I did read the OP and is a nice fanfic writing.
It includes multiple nonsensical things like falsely claiming that an "activist investor" can fire the CEO of a company when they only (supposedly, because they don't own that) have 14% of its stocks of such company.
As I mentioned before, they don't own 14% of Square Enix:

I mentioned WB just as a random example to illustrated that random people claiming to have stocks in a company and making a guess or suggesting something regarding an acquisition doesn't have absolutely no influence in the actions of that company. Even if they include 100 pages full of charts that have mostly fake data ,like in this case.
If they own any Square Enix stock at all, it must be under 2.28% of the stocks.
And well, even if it would be true that they have 14%, this wouldn't be enough to fire the CEO or to force to sell the company. Things don't work like that.
PS: That Yasuhiro Fukushima with over 25% of Square Enix is the founder of Enix and honorary chairman of SE.
