@hayhoras is said , i dont believe in too much what respawn officially announces, starting with broken promises and ending in phony blogposts about the Matchmaking that already have been debunked by Dataminers.
Also the ever reappearing rank penalty disappearing (this happens quite often , i encountered it at least 6-7 times over several seasons ...) all of a sudden without any updates surrounding and being reinstated in the matter of hours if i post smth about it ... seems quite funny and doesnt really look like a bug but rather on intention.
There also wont be a developer that spills the beans due to hefty NDAs and the risk of not being hired by a major studio anymore.
The entertainment industry has quite a history in rigging shows to please the crowd (Wrestling anyone ?!?!). To give one famous example :

I only know that much : If there is a way to raise profits, it will be done.
Worked in the Browsergames Industry some years ago, rigging the playfield was part of the Job ... if a good paying customer didnt do to well , we had to make him doing well to keep the money flowing ...
