My opinion is that NSA has already done that a long time ago. My opinion is that Iaws like this are made to provide cover to use that intelligence they have gathered in a less covert manner.

If somebody asks, "where the hell did you get that information"? They can point to this law as a legal procedure.

I dont think general encryption is a big problem for the NSA either, thought that is less certain.

The NSO group is able to repeatedly find serious and scary 0 days, that remain unknown for some period of time.

The NSO grop does not have the manpower, skill, budget and hardware that the NSA does.

I am convinced the NSA is sitting on an ample collection of useful 0-days, 0 click vulnerabilities and they can access Windows/Linux/MacOS/iOS/Android/Chrome/Edge/Firefox Dropbox,OneDrive,Box,S3, etc etc at their leisure. but they cannot use a lot of what they find since it would raise questions.
