Elon Musk recently launched Twitter Blue, a subscription that allows users to pay for a verified check mark and access other benefits.

The hope was that Blue would make Twitter profitable after the company has been sinking for years.

However, the advertised subscription prices in the European Union neglect to include taxes, and an EU consumer protection watchdog says this breaches fair business pricing rules.

Because of the way the subscription price is listed and the way taxes work in the EU, Twitter users in Europe considering the subscription wouldn’t know that it’s actually $20 higher per year thatn listed until they get to the final checkout page where the tax is added automatically.

A spokesperson for the European Consumer Centre in Ireland spoke to multiple legal staffers in ECC’s across the EU, getting responses for Belgium, Germany, Croatia, Ireland and Malta. The spokesperson told Business Insider, “I can confirm that the pricing display and associated promotions are in breach of Articles 6 and 7 of the ‘unfair business-to-consumer commercial practices’ directive.”
