Also, a lot of people feel that the government (in a Western/Northern European country) is mostly trying to protect its society even if some actions are misguided, while it's hard to make a statement about the benevolence of large corporations. Governments ought to be loyal to its citizens, while corporations only answer to their shareholders; their actions have no moral leeway nor are they beneficial to the majority of people. Facebook is not trying to protect society, it's trying to benefit from it.
