Oh no, the tweets you are posting publicly for everyone to see will be seen by ML. The actual bad part was shutting down API access to supposedly restrict 3rd party AI training. That completely killed the 3rd party clients, which is the only way I ever used it. 

You shouldn't be angry about AI training on your speech. I hope all my notes are read by all the parties undoubtedly training LLMs on nostr. If you are posting your world views publicly for everyone to see, you should want AIs to see it, because it will incrementally bias their outputs to be closer to your opinions.
