Posting images of text is not posting text. It is posting images. Posting an image of a dog is posting an image, not posting a dog. (Ceci n’est pas un pipe) If you posted an image that triggered an injection bug in their backend and filled a tweet with more than 280 characters, that would be circumvention. But there is no technical limitation preventing people from posting images of text, or dogs. Similarly, the alt text box allowing up to 1000 characters is not a circumvention of tweets only allowing 280 characters. You are allowed to write up to 1000 characters of alt text. You are allowed to post images.
