But when you say we should start using alternative tools in parallel to FB so that we contribute to grow these networks and reduce our dependence, then it's suddenly a huge cumbersome task.

Let's admit that the vast majority of users is actually ok with what FB does with their data. Showing concerns about privacy without actually doing anything is a cheap way of looking good.

Perhaps some of the things Facebook does can be done better by other companies.

They don’t need to ‘beat’ Facebook as a whole, and if the engineers motivations are the features they work on, perhaps they can get more satisfaction elsewhere.
