Is it censorship or editorial?
restricting is censorship. justified in plenty of cases; only the USA-ians die about free speech airing an opinion that may or may not reflect the opinions of the writer / user / parent organization is an editorial.

Are the companies building and publishing these models not entitled to choose what information they wish to train them on? Or should they be forced to train on anything anyone may want the model to spit out later? What about the people who want to prevent these same companies from training on their works?
