The thing is, is that this guy has been documenting shit since the 90's. Why the raid now?
Disclosure, that's why. Look at the continuously delayed congressional report. Bet many of you haven't heard of that.
There are people in the highest levels of the US Military who don't want it to happen. There are people who do. We can only wait and see if Full Disclosure happens.
It's likely that the timing have a lot more to do with the messy situation in Ukraine, and a general ramp up in testing of illegally acquired Russian equipment or a reactivation of cold war period sig int projects, then anything related to extra terrestrials.
Add to that that the FBI is back in red scare mode and suddenly you have a situation where the authorities are willing to bend and break a few rules in order chase various paranoid conspiracy theories about how every non-aligned outlet is a secretly working for The Kremlin.
Literally everyone on the internet is aware of the UFO disclosures and congressional inquiry, even non tech people. You have to have lived under a rock to have missed it, and it doesn't make you special for having heard about it.
