It's pretty serendipitous, actually.
The past month I've done a somewhat deep dive into LoRa for a project.
I ultimately dismissed it due to the data rates, but for simple remote controls or for sensors - things that report a couple bytes - it seems awesome.
I'm sure you can squeeze higher data rates out of it, but when I evaluated it I decided to go with a hardwired network link (I had to have stability, dropped info wasn't an option. But the client had a strong preference for wireless)

WiFi uses BPSK/QPSK/OFDM/OFDMA modulation.
LoRa uses CSS modulation.

This is about hacking WiFi hardware to make WiFi modulated signal intelligible to a receiver expecting CSS modulation, and have the WiFi hardware demodulate a CSS signal.
Thus making WiFi chips work with LoRa chips.

LoRa doesn't care about the carrier frequency.
So the fact that it's LoRa at 2.4ghz doesn't matter. It's still LoRa.

I'm sure there will be a use for this at some point.
Certainly useful for directly interfacing with LoRa devices from a laptop.
I feel that anyone actually deploying LoRa IoT would be working at a lower level than "throw a laptop at it" kinda thing

It's LoRa on 2.4ghz.
It's just that chirp signals are easy to decode from a lot of noise.
And they don't really affect most other modulation techniques. I think you can even have multiple CSS coded signals on the same frequency, as long as they are configured slightly differently.

LoRa is incredibly resilient.
It's just really really slow

The issue is with how aggressive Microsoft is about it.

Trying to download chrome? "Hey, are you sure you don't want to try Edge?".
Changing default browser? "Hey, are you sure you don't want to try Edge?".
Windows update... "We've done you a solid, because we know you want to use Edge".
I'm sure at one point, it was a warning in the security center that you aren't using Edge.
Also Teams (in sure there are others) will open links in Edge, despite what default browser you have set.

One of those morality Vs legality thing.
For it to be illegal it seems like the system needs to change

It's why no one can ever travel to the south pole, thus all videos/pictures of a 24 hour sun at the south pole are faked, so no one can prove the earth is not flat.
It's something like that.
There may be another backflip before the dismount to complete the Olympic grade mental gymnastics

Just point to the dictionary. "Draw your own conclusions, bro"

And there have been 5 people banned from GitHub due to racist and homophobic slurs, which violates Godot CoC and GH ToS.
I don't think these users were providing valid criticism. Never mind the fact that GH issues are not really the place to complain about some twitter drama.

Racist and sexist slurs, most likely.
You know, edgy 14 year old kids on xbox

However https://lobste.rs/s/wh6yhk/why_we_run_freebsd_current_at_netflix has some more discussion.

Seems like BSD was the right answer when they started running a CDN. They developed a strong BSD team that contributes to upstream. At this point, retooling to use another OS is probably a massive investment for questionable gain (like, what would the benefits be?!).

Ultimately, they chose BSD, developed BSD, contributed to BSD.
At this point, it's a custom shoe they have helped design, and it fits like a glove. Or something

pfSense and OPNsense are both BSD, and they are pretty popular routing/firewall systems.
BSD also has jails, which are pretty popular.
Netflix uses FreeBSD for some of their systems.
PS4 was based on FreeBSD.

I don't think it's on it's way out.
It still has a place

Server hardware does.
I think dell Rx30 are only just getting to EOL, and it was released in 2015.

Although, buying an Rx30 before 5 years ago would be in the 10s of thousands.
Refurbished Rx40 and Rx50 are somewhat affordable.
