I don’t disagree with you, but I’ve a question: This forum (along with millions of other websites) uses google-analytics.com, which means that, every time you use it, Google is aware of it. Would you warn people about that, too?
The way I deal with it personally is to use uMatrix to block the analytics, not just on this website but on all of them.
In other words, the sane position to take these days is to assume that everything is tracking you, and then take measures against that according to your principles. While it’s unfortunate that Julia is no longer an exception to the rule, the tracking that they do is as innocous as can be.
In the hypothetical scenario that I could decide whether to get rid of google analytics in discourse, or tracking in Pkg.jl, I’d get rid of google analytics without hesitation.
