Huawei got entity listed for selling to Iran (which Nokia and many other western companies does as well). There has never been any evidence proving Huawei espionage activity, which it can obviously be used for. Only Huawei gear has enabled foreign govs to undermine US espionage / influence efforts, iirc Huawei tech helping some african country using lawful intercept technologies to bust US aligned activists.
Nobody said about sanctions after arming Taiwan. It is just your guess. But about sanctions against Huawei, exists juridical cases and official statements.
Could you remember any case where US use sanctions without juridical case?
