Not every organization that is either behind the 8-ball on their MySQL scalability projects or who is suffering incidents as a result is making headlines. That’s just a fact, and you’re just going to have to accept that you don’t know everything.
And frankly, given your attitude on this, I think you’re going to need to present some bona fides for anyone to take you seriously. Maybe you can even convince GitHub to hire you and solve their problems. I bet they’d be happy to listen to you berate them on how pathetic they are.
