Both are customers though. As long as there is paying tier on the end user side, it is also a customer who has a presence in the decision that are made.
To Google’s credit, Youtube Red for instance goes in that direction. Same for Google Suite customers, Google Play users etc.
Of course the power balance is tipped toward the companies who are willing to pay more, but that’s a balance, and not a one sided relation.
For facebook I think the picture is darker, but then that’s facebook afterall.
