Yes, exactly! Also developers still thinking in dollars need to understand the rest of the world seriously! The income levels all around the world are very less in the developing countries. This is a significant factor. If I'm earning only 100$/month I would definitely not pay a cent for a service that promises 'privacy'. I need to survive first and if I'm able to do stuff for free I'm definitely using it. Those people are least bothered about privacy. An anecdote from a recent experience: I'm in India and there is the Aadhar project which assigns unique id to every citizen. There is a big privacy debate about it in the cities regarding privacy issues as the govt is forcing everyone to link our assets and tax numbers to it. People in the villages have no idea about it and there were pamphlets of Aadhar numbers being used as tissue papers in a local snack shops. But they all have a Facebook account for sure. People don't understand understand privacy when they just want to survive.
