Being a consumer rather than a producer of tech is strictly a business decision. There's significant cost to producing and maintaining a language, and Ericsson no longer wanted to pay the upkeep. That's not necessarily an indictment on the language itself. The alternative would have been to keep using it while also open sourcing it, but I'm guessing they just wanted to be able to hire cheaper C developers or whatever the flavor of the time was.
