The article contains a technical explanation... Don't be lazy and dismissive. It also explains that Segwit fixes the malleability and that Flexible Transactions also does (but in a non hacky way), so what is your point?
My point is that you don't understand what you are talking about and are feeding us FUD based bullshit. And you have failed to give an explanation when called on it, just linking to someone else (also ignorant) as "proof".
You obviously have no idea what the maleability problem is and you didn't read and understand the linked articles.
