I think the question isn't "does disruptor camo work" (it does), but "do people buy disruptor camo jersies for that purpose?" My guess is probably not. I suspect they buy it more because they like the look of camo or, possibly, to signal to other cyclists that they like to hunt or whatever signals camo sends to others.
As for the "stop worrying about what others wear" comments, those strike me as specious. It's certainly fine to ask for insight into why others wear what they wear without it constituting "worrying" or "insecurity." You "worry" about what other people wear and they "worry" about you worrying about it. That's a lot of worrying
