Just based on the above quote, it looks like Biden is just taking a wait-and-see approach to things he probably doesn't know much about--and remember, he has to unfuck a lot of what Trump fucked up in the country and that's going to take some time.
That is what you get when younger generations elect the older generation to lead the country that they are living in, they would need to catch up to speed if they want to learn something new. 4 years will not be enough to undo all of the damage.
But privacy? Sad to say, but it's dying. Not just in the US but all over the world--look at how many CCTV cameras England has, and how much power the governments of N. Korea and China have over their citizens' data. Unless people revolt, that trend isn't going to reverse itself, and in order for people to revolt, they actually have to care. Seems to me like most people don't give two craps about their privacy. Look at all the stuff people post on FB and other social media sites. You think the government/law enforcement isn't watching all of that?
Have to say that it is already dead, proponents of privacy have long been gone and the remaining ones are living on the mercy of the people that still value their privacy. I already accepted that my data has been sold to companies around to world to bombard me with ads, the only way to be a private person is to live off the grid. The government does not watch all those things but they are gathering it nonetheless to help them in the future in the case that they need to profile you, if they were to watch those, I feel like we should have seen a rise in the cases of cyber extortion.
USA was never privacy friendly in the first place, remember Edward Snowden, Julian Assange, Gary Webb and other journalists and whistleblowers killed by CIA. We are living in a dystopian future and the media is feeding us the lies that this is the utopia that we have been longing for.
