As someone who doesn't live in the US I'm not sure that that's not any different than the recent Crypto AG news, or the similar back doors that have been discovered in Cisco hardware over the years, including the ones provided for US 'law enforcement'.
The only real answer though is not to worry about this stuff, use the cheapest switching hardware you can find (sure use Huawei if they're the cheapest) and own your own privacy, don't trust anyone and do your own end-to-end encryption.
