Your LinkedIn data will be used for training
LinkedIn says it will start training Microsoft’s AI on profiles, posts, resumes and public activities on the site from November 3, 2025 — and it’s enabled by default. There is an opt-out option, but that only works on future content after you click it, and everything written before that will be used. It affects all users, including in the EU, the EEA, in Switzerland, Canada, Hong Kong, the UK, and also in the USA. Here’s a helpful page on the consequences and how to fight it.
