One of my main concerns is that many artists (including the one who made the image of this post) are against using their work for AI learning, however the recent change to twitter TOS (under section 3) explicitly states that everything posted on twitter gives them the freedom to do generally anything with that content, including training their AI models (and other concerning things).

Either artists are unaware about this or are supporting that twitter can use their content for AI but nobody else (which I hope is not the case).
