Elon Musk has defended his Twitter subscription plan after it was criticised by Star Trek actor William Shatner.After acquiring the social media platform in late 2022, the billionaire introduced Twitter Blue, a service that allows anyone to purchase a blue tick/verified account for a monthly subscription fee.Previously, blue ticks were typically given to notable accounts, such as high-profile figures, celebrities, major companies, politicians and members of the media.However, as part of his new plan, Musk has warned that these “legacy accounts” – those who received blue ticks before his takeover – will lose their verified status unless they pay the monthly subscription fee.“Hey @elonmusk, what’s this about blue checks going away unless we pay Twitter?” Shatner tweeted Musk on Saturday (March 25).“I’ve been here for 15 years giving my [time] & witty thoughts all for bupkis. Now you’re telling me that I have to pay for something you gave me for free? What is this-the Colombia Records & Tape Club?”In defence of his new program, Musk wrote: “It’s more about treating everyone equally.
