I'm aware that "national security" is often invoked in these types of discussions, and a little aware more than I think the general populace at how valuable some of this data is to intelligence operations. However, I would counter that by saying perhaps someone should consider whether it's a problem that such "critical" national security functions belong in the hands of companies that control the flow of such data for profit to anyone with a pocketbook, and ponder whether this is actually working to cause net help or harm for national security. I would argue strongly the latter, to the profitability of the people that control such data and contribute a lot of money to the elections of people that put forth their agendas, but this isn't the place to do so.

These are just a couple of fun examples, obviously you could augment these with LLM/DL tools and other anti-censorship (mixer, DCnets etc ), bot(nets) tools to create multiple identities that post in other languages, create fake photos of your in various countries, to make it hard to follow.
