Is ActivityPub logging which IP I post from?
That depends on the implementation.
Is ActivityPub monitoring which communities I view?
That depends on the implementation.
Is ActivityPub blocking me from browsing with my VPN on?
That—believe it or not—depends on the implementation.
We already have an implementation. You me and OP are all on Lemmy. So can you answer these in the context of Lemmy again?
I actually can’t answer them, because I only admin this instance, I don’t run it.
While I’m sure this is not the case, it’s entirely possible that the people who do run this instance are running a fork of it that does all of those things. It couldn’t log your IP address or block your VPN, but it could mine, and your instance could yours. And I haven’t read the Lemmy source code, so I don’t know what even an unmodified Lemmy logs.
(Actually this instance is running a fork right now, or rather a branch: 0.19.6-beta1, because lemmy.ml is the core Lemmy developers’ instance for testing beta code before releasing production versions.)
But you can read the source code and get an understanding of whether it is collecting private information or not. You can theoretically also fork the code and make your own version of Lemmy where you’re ripped out the parts that collect private information. Can you do any of those things with Reddit? Absolutely not. You have no idea what exactly Reddit collects and even if you did you have no control over that collection.
What you’re doing is questioning the privacy aspect without putting in the effort to check if your questioning is valid. Nobody is preventing you from reading the source code. And if you don’t trust anyone else running the instance you can fork Lemmy, make whatever privacy changes you need and host your own instance. That goes beyond the capabilities of the average user but that’s the catch with privacy, if you can’t trust others then you have to learn more to get by without others.
