This isn't even remotely close to the gambler's fallacy. This isn't an issue of statistics, or probabilities being skewed 'this time'. Really what the question being asked is if you want to force people by law to hand
more information over to organizations like
Facebook. Legislation or not, Facebook and their ilk
will abuse this data. Give it time, and so will any government. Your argument is basically "yeah, well it's so bad at this point we might as well not even try to stop it".

Anonymity isn't something you can just do away with and have a happy ending. In some parts of the world, anonymity is the only thing standing between people and their government. That's not something I'd like to see done away with. The Afghan people need anonymity now more than nearly anyone else in the world. As do the Chinese, the Turkmens, Eritreans, domestic violence victims, and anyone who lives in a world where being identified could lead to a swift, brutal death. What are these folks to do? Hide forever? If that's the result, then we are not just seeing social cooling, we're looking at a social ice age.
