Ask HN: What network equipment to buy to avoid backdoors?

I want to buy network equipment for my home, but I don't want there to be existing backdoors or backdoors added later. I am concerned a company like Eero for example could be persuaded by some three letter agency to add a backdoor that can be used to snoop my network traffic. Are there good open source options?

I'm looking at https://teklager.se/ for routers. But I can't find any good options for wireless access points?

Thanks for your help!
