So? This feature is available to everyone and you have zero idea how many people actually use it.
If I go to one of your GPL projects and I ask a simple question to find out what this project is about, you will be perfectly "ok" that this interaction (that includes most of the code that is required to answer my dumb the question) will be used for training?
Nobody in this subthread is saying if it's OK or not. We're just saying that it's very useful to know that this is what they're specifically collecting. Jiminy.
