It’s not clear at this point how users can opt out of this. There doesn’t appear to be a control for opting out of data sharing for AI in the settings menu of the X app. It may be located in the “Data sharing and personalization” option in the “Privacy and safety” section, but for now, there are no indications about AI use of the data yet. I’m inclined to believe the setting will appear before the new policy enters into effect.
Licensing data to other companies can become a significant new revenue stream for X, which is reportedly currently experiencing waning interest from some of the major advertisers.
X has also updated its terms of service with stricter penalties for people who are caught “scraping” large numbers of tweets. Anyone viewing or accessing more than a million posts a day will be subject to a penalty of $15,000.
X owner Elon Musk has been vocal about his disdain for “scraping” (collecting data from the internet to incorporate in spreadsheets for whatever use) of data. The company temporarily blocked logged-out users from viewing tweets in an attempt to block scraping last year.
I personally dislike my data being used to train AI and would most likely opt out of sharing it when the setting becomes available.
