Well, it finally happened. After several legal snags and a full-blown trial, Elon Musk bought Twitter for $44 billion.  One of Musk’s first priorities as the owner of the social media giant is to change Twitter Blue. Twitter Blue is an optional $4.99-per-month subscription that Twitter launched last year. Subscribers currently get an edit button, ad-free access to some news sources, a feed of popular articles from the people they follow and a few other features.
