I'm not all that sure it wasn't all that popular for Wide and Metropolitan
backbone infrastructure fabrics; finance, rail and automobile signalling
and routing come to mind. Nor do I assume that those area's are uniformly
operationally current. That's for the bots and RAT Trojans in the global
data stream to check for and perhaps exploit.

I can't say for sure whether token ring on optical networks has left the
IoT entirely. Fiber and associated hardware is still very expensive. In
some process and control systems redundancy and fail-over take necessary
priority. Gigabit-speeds are not necessarily more desirable than trust in
those resource sharing networks. Depending on location in the world and
size and purpose of actual needs, I think some places in this world wide
web, might be still be paying off the amortized cost of the original cards
and cables of optical token rings, and even employing recycled and new old
stock products, but that's just my opinion
