I've been a web user since the early 90s and I honestly that we are going a little astray from the original spirit of the web. Back then, it didn't matter what you posted, anonymity was the default and people used to say that no personal information should ever be shared. This move by the United States government feels like they are crossing the Rubicon towards a highly regulated and almost dystopian view of the web.
It is my opinion and I think a lot of others on HN would agree that privacy should be the norm. Certainly, law enforcement has a right in some cases to extra information but when governments are able to reach across the ocean and pluck personal data from each other then there is a serious problem. This happened to my friend who ran a startup in the financial sector who was compelled to reveal a user's data. There was no recompense for him as he didn't have the resources of a big company like Microsoft at his disposal.
Tech companies and law enforcement should more of a conversation about these issues before they are forcibly put into law.
