The good news, for all involved, is that Microsoft no longer supports MSFS, so
the advantages and difficulties that those of us flying the real system face
will be completely lost on MSFS users like MX, hopelessly lost in a 1980's
world of air traffic regulation.

Serious simmers do not use the built-in ATC of MSFS. And the product is still
supported, although it is no longer under active development. Were it to
disappear, there are alternatives such as X-Plane (not a pretty alternative,
I'll grant).

But none of this has anything to do with ADS-B.
