I would love for Mozilla to fix this, which is why I try to be pragmatic and concrete. But so far, they don’t seem willing to do so.
Here's the problem - people don't care if the information is there or not. Microsoft has been disclosing their required telemetry data for years and people still thing it's an invasion of their privacy.
Take you for example - I gave you a source, you checked 1/3rd of the information in it and started complaining.
Why am I assuming you didn't bother to read the whole thing? Because you're claiming that "technical data" is too obscure of a term to figure out what it is. "Interaction Data", in your words, "can be literally a keylogger", right? Well, it's very clearly defined in the table:
Click counts, impression data, attribution data, how many searches performed, time on page, ad and sponsored tile clicks.
Which of these would you consider to be "literally a keylogger", hmm?
