I guess it raises a fundamental question: If not ads, what else would Facebook male money off? Running the operations is costly and something has to pay for it.

I am aware that Norways ban is temporary (and I'm hella glad that at least the EU/European countries stand up to big tech on data security), but just not allowing the use of user data will probably not work as a solution.

Wikipedia's model sounds nice, but the cost of operations are by magnitudes different. I think it's a question that will also affect other platforms (like it did affect reddit and will affect Lemmy at some point).
