Yes. Or, again, I don't know. That's the terrifying part. But given that we know the surveillance machine is much deeper than we anticipated, I can't come up with a worst case scenario anymore, which is what scares me the most.
Personally, I fear writing certain things with a username that's easily associated to my real name by the public at large, not the government with their clever tools. That's because I know the real and not-so-improbable consequences of doing so[0]: losing my job and getting blacklisted from the entire industry I've spent most my life trying to improve in and contribute to. It can be economic death. The threat of the mob is much realer to me than the threat of the government.
