You’re right. The consumer tech consequences of the chip ban is more important than the military implications will ever be. Huawei’s lost tax revenue cost the Chinese government billions, which itself does more damage to the Chinese military budget than semiconductor bans for systems which aren’t actually critical in a conventional war. Cruise missiles can work effectively with tech from the 70s, and you don’t need 5nm chips to guide a rocket into an aircraft carrier. And this was about Huawei specifically - look at Huawei’s global smartphone market share. Pre trade war they were on par with apple and samsung volumes, with margins and a lineup closer to apple. Then the 5G bans and a PR campaign crippled their international sales, and semiconductor bans cratered their overall production.

Other Chinese brands like Lenovo, xiaomi, and the BBK brands (oppo, vivo, one plus, realme) are doing fine though, because inside them is all snapdragon, Qualcomm, intel, nvidia, and AMD. They’re basically final assembly plants for component manufacturers ultimately based in the US, whereas Huawei were using their own kirin chips, were taking market share from apple, and were creating their own operating system called HarmonyOS to replace android. Basically every major consumer tech hardware company in the US stood to gain from Huawei being taken out, including the US government when the trump admin used it as the poster child of the trade war. Huawei’s PLA connections were a nice bonus to sell to the public, but this was first and foremost a state backed corporate hit job.

And the worst part is, because of the opaqueness of it all and combined with propaganda from every direction, it’s hard to get a handle on how justified any part of it actually was. Because you basically have to choose to either trust the trump admin, US government, and corporate America, or Huawei and the Chinese communist party, and I don’t trust any of them. Personally I’m going with, there was probably something to be concerned about, but probably at a similar level to buying US hardware which the us government has clearly signaled that they have back doors into, but the corporate power struggle for market share is the actual reason behind it all.
