Scala's Gitter-to-Discord migration mistake

>Information on Gitter is public, it does not require an account to read; >Information on Gitter can be linked from across the web; >Information on Gitter being public, is indexed by search engines and is being archived;

Regarding these points, is this really a necessity when the Scala community seems to have a public Discourse for both users [1] and developers [2]? A real time chat is not really an ideal place for information to be stored in the long term, forums would be a far better place for that. A chat would typically be for here and now discussions about Scala, and any one off issues people may need help with, what with the forum serving the more long form discussions that would benefit from being indexable by a search engine.
