The new and updated data-sharing options will be released in the next couple of weeks with the upcoming 2025.2.4 update of JetBrains IDEs. Non-commercial users will get a notification about the updates in the terms of use. For holders of other types of licenses, if you never provided consent, nothing will change.
The OPs quote looks pretty honest to me. This is right from the link:
Right, but its OPT-IN by default. Thats bad company behavior. Let users choose if they want to OPT-IN. Don’t turn it on for your users without their consent.
OP did not say those users are fucked. If I’m mistaken, please point out where they did.
