What do #Meta get from harvesting all that #Threads and #Fediverse data?

Well, they can build a detailed profile on your interests.

What value do they get from knowing your interests?

Well, with this data, they can nano-target you. That is, with no other PII, they can individually identify you.

This can get pretty nasty, pretty fast.

EU's DMA and other related laws are our shield. Other countries should take note. We must remain vigilant to the coming storm.
