Oh, you think? The US have a habit of imposing sanctions on companies that don't respect their prohibitions- so for example they decided that companies cannot offer services to a certain EU citizen in the EU otherwise they'll be in a sea of troubles. In theory, imposing these so called "secondary sanctions" is against international law; in practice, the EU is so spineless that doesn't even dare to protest.

That does not make it illegal in other countries, which was the claim.

Technically, not illegal.

Practically, the sanctions/restrictions will be imposed, due to fear of losing access to US market/US infrastructure.
