I like this thread for asking questions about MMR. However this is a false equivalency:
On the one side, we have players who understand the concept of handicapping and deny that Blizzard has the right to secretly rig their ranked matches. On the other side we have a soulless corporation trying to make their product as addictive as possible by any means necessary in the pursuit of profit, denying the existence of the handicapping system by omitting any mention of it from their users. These are not equivalent forms of denial, and the latter is deeply wrong.
And we have the words of Scott Mercer, lead designer of Overwatch, confirming that this is the case:
This is not a case of “neither side can prove.” The issue is proven.
