We do it in a non-commercial nature. Meta does it in the hope of building a market, estasblishing paywalls and eventually turning a profit - all the while never paying the original creators.

This is exactly what they (and Google and many others) do with personal user data. We manufacture the data, they collect it without due consideration (payment) and use it to profit so much that they've become some of the wealthiest businesses in the world. They've robbed us via deceptive fine print, why wouldn't they think they can get away with this also?
