It is wildly disingenuous to just copy paste that line from wikipedia and not the rest of the paragraph.

> In February 1998, Ericsson Radio Systems banned the in-house use of Erlang for new products, citing a preference for non-proprietary languages.[15] The ban caused Armstrong and others to make plans to leave Ericsson.[16] In March 1998 Ericsson announced the AXD301 switch,[8] containing over a million lines of Erlang and reported to achieve a high availability of nine "9"s.[17] In December 1998, the implementation of Erlang was open-sourced and most of the Erlang team resigned to form a new company, Bluetail AB.[8] Ericsson eventually relaxed the ban and re-hired Armstrong in 2004.

- edit, poster was quoting a quote in the article, not wikipedia, the article is the one omitting the context
