Question about the randomness of mm.

First of all, I'M NOT SAYING MM IS RIGGED SO TROLLS GET LOST.

I see many people saying either it's rigged or it's not rigged. Like with losing streaks, it happens more often than not for the majority of us, it could be pure randomness (but y'all got to admit sometimes it's abit sus) and I see lots of people complaining about it. With posts like those, comes replies saying that the mm isn't rigged and it's random.

I want to ask those people who says the mm isn't rigged:
1. Why do you say that? How are you so sure? Like those people who say it's rigged has their "proof" (losing streaks) to back it up. What's yours?

1. Why wouldn't wg rigged the mm? Practically thinking, it's the perfect business strategy to keep their targeted demographics happy. It would be almost idiotic not to implement this. The alternative is that wg doesn't rig the mm out of the kindness of their heart.

To those who intend to answer, please don't "answer" with an insult towards me personally (y'all know what/who I'm talking about) or a comment that isn't constructive and doesn't answer my questions. I'm open to all opinions and I look forward to learning your perspective.
