Huawei, Foreign gambling sites were banned on dubious reasons in 2006 (in reality American companies weren't as competitive and las Vegas needed to be protected), Japanese electronic tariffs in the 80s/90s ...

US never exactly believe in full on 'free trade'.

See the Chicken tax for trucks for a not so recent example https://en.wikipedia.org/wiki/Chicken_tax

I think that's a bit different. The crypto-wars were about restricting strong encryption IN GENERAL. Not targeting a specific vendor.

The equivalent would be to restrict all LLMs with a minimum number of weights.

DJI, Huawei and the list goes on. Definitely no need to go back "25 years". The USG is turning into a joke of a surveillance state. As if any of the US based tech is truly any less backdoor'd? Cisco and Flock and Google and Facebook and Microsoft, oh what amazing technology companies that could never be used for... Oh wait, what a fantastic endgame we're on course for! I wonder why other nations are actively moving away from US tech?

TikTok ban was the worst one because it was about speech, not trade or security. If the bill said "China banned our social media so we're gonna ban theirs in reciprocity," that'd be a way more valid reason.
