As a software engineer who works closely with electrical and firmware engineers I know what you are saying is completely true.
The question is how did we let it go this far? Why has there never been serious Western alternatives to JLCPCB, PCBWay, JLCCNC etc.? Has anyone asked themselves how these Chinese firms are so cheap? How can JLCCNC take ~$120 worth of raw material, CNC machine it into our specified part, anodize the part, and send it to Denmark for ~$120? Like what is going on?
I get how there is risk associated with a supply chain attack, but what are you going to do when you don't understand a vulnerability and need to fix it?
Most problems aren't impossible to solve of course, but those who've been working with a codebase for a long time probably have a more intimate knowledge of how it works.
Not sure where I'm really going with this other than I fully understand opsec, the hacker mindset, cyber security, etc, but I've never really cared to stay private because I wanted to be known. Now that I'm likely as good as I'll ever be, it doesn't really matter lol. If someone finds something I said in poor taste, I'll apologize and hopefully have learned from it and move on.

I already have an rtl-sdr picking up aircraft beacons and have this antenna on my todo list. Are there any benefits to buying a grid antenna vs DIYing my own helix?
