But will the "big fine" be more than the money LinkedIn will make by doing this?
Even if it was free I wouldn't include it in AI training.
Its a really stupid time to test the EU over something that cant have much net value to LinkedIn - a 1bn EUR fine (approx 4% of LinkedIns revenue) is well within the current internal "cap" the EU have reached with issuance of fines.
But who knows. The EU is much more patient than I, and prefers boiling frogs to scalding them.
