As it says in the title, the BBC is starting its own Mastodon instance. I think the CBC (and other news networks) should do similar. Particularly with the recent passing of Bill C-18 it seems like a world where the links we share are crossposts to news organizationโs own content is the perfect resolution to that whole issue.
News publishers like BBC and CBC could also repurpose their RSS feeds, by creating individual accounts on their own Mastodon for each of the topics and make the same rss content available through there. This would make it easy for users to sub to news they are interested in: https://www.cbc.ca/rss/
