That doesn't help if you're trying to be safe from a powerful world government - one with the resources and will to infiltrate an open project for its own ends. It's far less likely that there are US backdoors in Huawei routers (which surely contain Chinese backdoors!) than in any mostly american open-source software you pick.

Huawei routers are well known to be backdoored by the Chinese government. If you’re worried about attacks from nations then you can only build things yourself from scratch, your next best option is things done in the open since the bar for hiding back doors is much higher.
