it’s closer to a serious article than a blogpost

I find it bizarre and plain wrong to imply that blog posts can’t be serious articles.

Are Trump and Musk fulfilling the prophecies of the endtime?

No.

the radios are cheap and work incredibly well

But they’re proprietary. Which is bad.

Edit: and to be clear, it’s not just that the radios are proprietary black boxes, which is bad, it’s also that by using them, you make it necessary for all other parties you communicate with to use matching proprietary black boxes, which is bad squared.

there isn’t much of a reason for someone to homebrew their own

Especially when there’s an existing, open standard for communication using the same principles.

the actual radios

Looks like we’re using different terminology. I mean the bits that take care of the RF part. The “chirp spread spectrum”. Perhaps “modem” would be a better word.

But regardless, whatever word you use to refer to it, it’s proprietary. And that’s bad.
