So, given Twitter is trying to use your content to train Grok, this is the best reason possible to kill your account there, because even though you can turn this stuff off, for now, what's stopping Adolf Musk from pulling an Adobe and turning this stuff on permanently, basically using your content to train Grok against your will, with no opt-out?

You'll be a lot better off moving your content to Mastodon or even ATproto (as in a third-party PDS such as Blacksky or even a self-hosted PDS, not bsky.social which is controlled by Bsky corporate and their questionable moderation choices) in terms of having actual control over it.
