You got a lot of relevant answers so I want to point out something else:
You’re hosting your own services. By yourself. Fuck everyone with a broom who tries to gatekeep that. And I don’t mean wooden side first.
Seriously, your question is on point here from my perspective and as long as it has a connection to running services by your own I personally would love more diversity in hosting solutions.
Personally, I’d love to see people share more about their provider agnostic opentofu deployment or someone who went all in on AWS lambdas for weird stuff.
All the claims concerning telemetry in that thread are made by the person “asking” the question.
I don’t understand the intent of this post. It looks like you’re trying to start a rumor to be honest.
Telemetry in Thunderbird exists and is well documented. If someone is not happy with their engine or approach they need to switch clients and not basically tell them “I want you to rebuild everything around my nerds”.
