Open Source Could Be a Casualty of the Trade War

When I heard that ARM was to stop doing business with Huawei, I was a little bit puzzled as to how that worked: ARM is a British company owned by a Japanese conglomerate; how was the US able to extend its influence beyond its citizens and borders?

If the US wants to sanction OSS out of existence, it's their loss.

It's not even possible, how does the US want to make that?

Have you read the link in the comment in replying to? The US is considering banning the use of OSS if some Chinese entities participated.

It's kind of galling that this isn't even the dumbest thing I've heard the US contemplate recently. We're living in really weird times.

>The US is considering banning the use of OSS

Yeah easy, the US is not the only OSS producer, if the US wants to make this, every software will have it's Chinese or European fork....have a nice Day US...once again you cut yourself.

ARM has a design center in the USA, which means they are under obligation to prove that their technology isn't illegally exported.

>have to follow a US sanctions regime.

Again look at the Premier members:
