It'd still be zero-config to provide it's primary function. I don't think anyone would say anything against MeiliSearch or not consider it zero-config had they decided to enable analytics off an env var rather than having analytics be sent by default.
I would like to clarify that by analytics we are only talking about 1 ping per day that sends a hash that allows us to uniquely identify a user. The privacy of the users is kept. It just serves us to know if our work is being used.

This is already pretty invasive - it discloses activity, number of machines deployed, IP address which identifies location and often organizations and individuals (and which is considered protected personal data per the GDPR afaik).
> The privacy of the users is kept.
No it isn't, see above - even as the authors you don't get to decide what data does or doesn't infringe upon the users privacy.

This is irrelevant, if you want to condition the use of your work on being let known where and how it is being used then license it accordingly and abide by the applicable laws.
