I think it came from a genuine place. You may not agree, and I understand your perspective, but I think there's two things Reddit believes that explain everything you've complained about.
First, that their app is a better mobile experience. And I'd agree, actually, but I understand why someone would disagree. From their perspective it's an easy download and it's native app and it's way better.
Secondly, the best way to build something good is to have more data. This involves tracking people. I think most people have two opposing options: tracking people sucks, and making product decisions in a vacuum is wrong. It's a tough balance.
I think most decisions are done without malice and without "suits" involved.
