Windows is not mature or safe enough to be used on the bare metal.
Sure it is.
Oh, wait, did you mean "... on the bare metal, on the Internet."?
OK, I see your point now.
... it opens up another surface for attacks.
I will probably install something like this at some point, but please don't put this on a non-isolated system without understanding the risks.
For communities relatively close to another community that already has or will soon have a good Internet connection such as from an undersea cable, microwave towers may provide an effective bridge.
This assumes reliable electrical power and the ability to construct tall-enough-to-see-each-other towers at both ends.
The combination of sea-port fiber connections and microwave connections to "nearby" communities should reduce the number of people who rely only on a single satellite connection, but it's not the solution for everyone: Setting up a microwave-tower network like the US had from the 1950s to the 1990s, with towers spaced every 30-or-so miles, would likely be cost-prohibitive due to lack of existing electrical or generator-fuel-delivery infrastructure.
Other than having two birds in the sky - either in orbit or flying around in the atmosphere - I don't see any way to give everyone redundancy without being cost-prohibitive.
By the way, for low-bandwidth communications such as voice-grade telephony, texting, and email, or even very simple/bandwidth-optimized web browsing (the modern-day equivalent of a BBS-connection or mainframe-TTY with local echo turned on), shortwave-or-lower-band terrestrial radio should be able to get the job done.
Not only is it not fit for its advertised purpose, it's unsafe to use.
