More cynically, this is may just be battle space prep for the run up to legislation giving the gov a backdoor into any E2E systems. The pretext being 'something something terrorism'.
Also, I commented this above, but there's a different way to solve the problems of polarization and radicalism. It involves solving people's material problems, and the US has been slowly getting worse at this and decaying for a while now. Instead, the political establishment is doubling down on surveillance, the silencing of dissent off of any platform with reach, and ultimately physical repression, through the increased funding and militarization of police.
Right now this is claimed to be targeted at the far right.. but it doesn't take a genius to compare the police reaction to BLM vs the capitol riot to see where it is going.
What is surprising to me is that the politicians and bureaucrats seem to think bad actors are supreme idiots. They aren't. The overt nature of a criminal mind whose cloaks themselves in church going taxpayer in suburbia is the reason why no agency in the world can predict tragic acts of domestic terrorism.
If someone is going to plan a Charlie hebdo-esque operation, no intelligence can help you. They can just meet at the park for a cold drink and discuss which weapons they are going to use. Intel agencies rely very much on tip offs from civilians and private interests like banks and shops/malls "guy came in looking dodgy and bought a ton of slightly dangerous stuff" kind of thing.
