> Sounds like some manager had drunk the FOSS/bazaar kool-aid at that point, but wanted to keep the costs down by just taking from FOSS efforts in other languages (as opposing to continue to use more resources to maintain Erlang at the previous degree, and giving to FOSS). AFAIU, nothing to do with FOSS, which wasn't really on the radar for a somewhat conservative telecom company at the time. It was about custom in-house stuff (PLEX, Erlang, etc.) vs. "industry standard" (C++, OO, UML, etc.).
