This should be a top-level post. It saddens me the sheer number of people who accept the TikTok banning blindly because "national security" (not here so much but people I've talked to at work/other forums). This vague terminology could be adapted to encompass any communication that might be a threat to "national security" including encryption.

Once the precedent is set it will be damn near impossible to go back; just look at the Patriot Act.
