It’s because this isn’t about privacy at all, it’s about a popular social media platform being outside the control of domestic intelligence agencies. The US is unable to control the narrative on TikTok the way they do on American social media, which allowed pro-palestinian sentiment to spread there unhindered. It had a huge effect on the politics of the younger generation (IMO a positive one) by showing them news and first hand accounts they wouldn’t have seen otherwise.

Edit: And yes, China is able to control the narrative on TikTok and that is a potential problem, but so far they’ve had a fairly hands-off approach to US TikTok aside from basic language censorship. I figure the way China sees it is that an unmoderated free-for-all will do more to sow divisions in the US than a carefully controlled (and therefore obvious) pro-China narrative ever could.

Imagine enforcing shitty copyright laws on yourself like some code of honor. We developed the technology to make infinite copies of any media and then spend endless resources fighting it because it undermines our parasitic economic model.

Imagine for a moment that society embraced the full potential of digital technology. We could have a library of all human art and knowledge ever produced available for free, instantly, everywhere. If book libraries didn’t already exist and were proposed today the excuses for rejecting it would be the same. The answer is also the same, change our economic model to support people’s basic needs unconditionally and directly subsidize the production we need/want (like art).

Craigslist was always on the fringes, before Facebook marketplace came in there were a bunch of separate and disconnected online marketplaces. Facebook marketplace had the advantage of already having a massive user base (larger than any of the existing online marketplaces), causing it to become the largest one right out the gate, which then of course makes it the most attractive option for sellers since they will reach more people.
