Of course psyops exist, but allowing tax-funded government agencies to decide what's a psyop and what isn't sounds even goofier. If a countries citizenry can't figure this out themselves, the solution isn't having the government decide for them, it's to fix the critical thinking problem.
You're arguing as if these organizations are just going around shutting off sources of information for saying the wrong things. That's not what's happening, as even "the wrong things" and even psyops are in fact protected by the 1st Amendment.
