What do people, especially people who are opposed to surveillance-based capitalism, think about UTM codes? I usually remove them except sometimes when they indicate a "mastodon" "campaign" and I actually want some of these sites (e.g., news sites) to recognize traffic is being driven from the Fediverse so they'll engage more here.

On the one hand, I generally appreciate that they're typically more transparent than some trackers that follow you from site to site. On the other hand, I think, "It's none of your business where I'm coming from." There could still be tracking on the back-end that I can't see and can only avoid with a VPN or something, but I'm always in favor of "not making it easy".
