No, what's happening is that people like NCOSE and Collective Shout are putting pressure on the processors. They've loudly bragged about it. It's not the first time they've done it. And they've been known to enlist government actors to help with the pressure ("Operation Choke Point").

Every time this issue comes up, a bunch of people crawl out of the woodwork trying to prove how "wise" they are by mouthing this idea about chargebacks. And the processors are happy to keep their heads down and not dispute it, or even encourage it, since they really want the whole issue to just go away.

Chargebacks are not the issue here, and if you haven't paid any attention at all to what's actually going on, you're best advised not to make yourself look like a fool by talking about what you guess might "most likely" be happening.
