X’s “X Premium” subscription program, formerly known as “Twitter Blue”, hasn’t been the solution that Elon Musk had initially hoped when he re-pitched the initiative late last year as a means to combat bots in the app, while also providing X with an alternate revenue stream. Thus far, X Premium take-up has remained very low, with only around 0.3% of X users signing up to the scheme, which gives you a blue checkmark for your profile, as well as a range of other add-on features.
