I'm guessing there's an unspoken assumption that given a UUID the server-side would not log IPs. It then comes down to trust that they'd stick to that.
I should probably get back into the Discourse thread to see if I can contribute constructively, but the amount of back and forth between mostly “My freedom!” and “Tū quoque!” [1] in the thread over the weekend – apart from me being far too busy to take the time to summarise it all – has kept me away, although it looks way better over the last few hours. With the little free time I have I would rather work on my Julia code. '^^
Also, I find this whole discussion to be somewhat irrelevant when talking about a service serving up arbitrary code to be executed on your machine: if you don’t trust the server owners, you really shouldn’t be executing the code they serve up.
