You dont have to use it.
neither do I, since I have my own.
but people are free to use mine if they care to trust me to not collect their XPUB.
i know the butthurt runs deep, but you can just let people make their decisions.
You could say that these guys behind https://dojobay.pw provide a service altruistically, but the thrust is that they collect your XPUBS.
This shitty circus of self-proclaimed privacy fighters (Samourai fans) that run honeypot servers and invite naive users to connect to them must end.

You know it is wrong. Did you inform @kyle-moore that by doing that you would be able to track all his past, present, and future transactions? How much money does that poor guy have?
Of course you did not. Otherwise, nobody would ever connect to any of those 20 or so servers maintained with the sole purpose of collecting uninformed people's xpubs.
If the xpubs collecting mafia were honest they would at least add a warning sign/text saying something like "By connecting to this server you accept that the maintainer can see all your finantial activity and your balance forever. Are you okay with that?"
