That doesn't many any sense, because I just specifically told you that it doesn't matter to anyone but you whether or not you use Jellyfin... If it mattered to me, then yeah, sure. I'd be a zealot. But I don't give a shit what you personally use.
Also, pointing out the fact that Jellyfin is pretty indisputably better for people in this specific space isn't zealotry. It's just good common sense.
I think you missed the part where I said that the zelots completely ignore the legitimate reason why people use it over JF. Same reason I use it.
Also you can literally opt out of the data sharing, the button is right there. And if you don't live in a corporate shit hole like the US, data protections make sure that they won't use it without your consent or even store it because it's protected PII.
