In light of the recent stuff about reciprocation, one possible campaign which could be started in 2018 would be something like "payback the content creators".

The silo companies obviously make massive profits out of the content created by users, but users typically get no financial remuneration for their labor. If a company like Facebook could be pressured into making some payouts then this would eat into their profits and hit Zuckerperson where it hurts.

On the other hand maybe this would be considered a smart move for the silos since it could lock users in even more effectively.
