If you prefer your content/ data not to be used to train LinkedIn’s AI, you can opt out at https://www.linkedin.com/mypreferences/d/settings/data-for-ai-improvement (but only until tomorrow, Nov 3rd?).
Crazy that this requires an explicit opt-out by the way, it really should be opt-in (so off by default).
More info about this can be found at tweakers.net by the way.
Feel free to share 😉
