You nailed it.
Facebook is nothing but a data mining company. People were upset that they were selling data....yet that is to be expected. They are very open about the revenues they make from this.
What was not open was the depth of their surveillance. People are now really upset. The question is will they really do anything about it? I highly doubt it. A few will leave but most will continue to be on there on a daily basis.
Evil is a word that is applicable here. These people want total control. The governments of the world should nail FB and Zuckerberg to the wall. Sadly, they will not.
We need to keep promoting STEEM as an alternative. Yes there are flaws on this blockchain but we are progressing in the proper direction. With greater development, people are going to have more options. We need interfaces from different countries, perhaps some that are not required by law to keep data (the KYC laws).
Either way, FB should be dead to a lot of people. Personally, I hope they never recover from this.
