Sorry, but I'm not sure you read or understood my comment. For example, the "muh freedumb" thing you talked about: I didn't say anything about freedoms, lack of freedoms, or governmental overreach. Not one single thing. What I said was that I don't know what information people would be angry about giving to the government but happy about giving to Facebook. If you see an argument about freedoms in my comment, I'd be very curious to see what led you there, because I didn't intend it.
I asked for examples, and you've provided one. Let's consider it. I don't know people who would be angry to put their phone number on a government form, assuming they're not already angry about having to fill out the form itself. I know a lot of people who would not put it on social media, exactly for the reasons you say: it's public when they have it, it's not when the government has it, and the government already knows it. However, as data goes, this is one of the less sensitive pieces of it. I've had my phone number for many years now, and since I'm able to port it around to different providers, it's likely to be mine for the rest of my life. I've had plenty of places who I've given it to, either because they actually needed it to contact me or because they demanded it and I couldn't do what I wanted or needed to do without them having it. This includes various government services, and I didn't mind them having it. This means that, almost certainly, my phone number and name are associated in nearly any dataset that can be purchased and likely in plenty of free ones to be found online. I have little hope of my phone number remaining truly anonymous, so I must factor that into how sensitively I'm going to protect it. I still wouldn't hand it out to anyone who asks, but I don't protect it the way I do more sensitive pieces of information.
The kind of thing that I don't want to give to governments are things like passwords to online accounts, private keys, and the like. Mostly, they are things I don't have to, although various ones suggest collecting them from time to time. I would not give any of those to social media either, and I think that, although there are a few people who would be stupid enough to fill in the form "The password to your email account here", it's a rather small set compared to those who are willing to give their phone number except for authentication and communication, which is a small set compared to those who use the services at all. Maybe you think of phone numbers differently than I do, but if you agree about its sensitivity, is that your only example?
