if you look at the latest release[0] there seems to be 33 contributors. While a bunch of the commits is made by Erlang/OTP(I assume this is Ericsson) it is not the 1990 anymore and a lot of tech like rabbitmq and couchdb uses erlang to reach "webscale" deployments.
Almost all these commits are from Ericsson employees. The community did start contributing bigger things in later years (the improved unicode support is a good example), but the core team is still very central to the development, and their main bug tracker is not open.
The article makes it sound like that team would not be affected: "However, the 14,000 employee-strong Swedish work force is to stay intact – at least all R&D engineers."
