Regarding spoiling the fun, were this a world without enshitification and/or corporate malfeasance that might be a good consideration. For the world we currently actually DO live in, my initial reaction is usually one of mistrust - and I strongly suspect I'm far from alone in that.
As such, I normally might've not ventured forth with exploring your offering, but instead waited for someone to give me more of an idea what I was walking into before potentiality giving out information I didn't want to inadvertently. However, at the moment I came across your post I guess I was feeling gregarious enough (and less concerned with this identity since I've only recently created it) to toss my normal inhibitions aside, and share the kind of info I myself would have been wanting to see before taking the risk.
TL;DR: There are an number of psychological factors at play here as well as real-world concerns, so IMHO the more up-front you are in letting potential users know what to expect, the more comfortable they'll be with giving it a shot. They'll also be better informed about what to look for in features they might not have otherwise discovered with a quick spin.

I'm not interested in debate of this topic, as virtually every time I have engaged in such in the past it's quickly become obvious that the other person was not engaging in good faith with an open mind.
There is plenty of information to be found from all sides on the topic on the net, and if you're truly interested you should invest the time to look it over with a skeptical eye while knowing there's a good amount of propaganda from both sides. You'll have to figure out which sources are most trustworthy, and factual in their reporting - although even the more biased sources often make good points to be considered. Then compare and contrast stories to find the essential facts that are most likely to actually be true and go from there.
Good luck.
