In this reply you you talked about "some breads", the OP Post only talks about bread - and that for sure had only ingredients in using at home.
Same for French fries: potato, salt, fat .
I'm with the poor downvoted fellow, I don't understand where the risk comes from when it's described this vague.
Are home made burgers better? Is it the freezing process and I should lower my meal prep? Is it additives?
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".
