LONDON (AP) -- Music streaming sites Spotify and Deezer are among European tech industry players calling on the EU to get tougher on unfair business practices by U.S. giants like Apple, Google and Amazon.
In a joint letter, the group urged European Union ministers to go beyond current proposals aimed at regulating online platforms that act as middlemen between customers and businesses.
They said that the regulation doesn't go far enough to ensure dominant tech companies avoid practices that "reinforce their privileged position or unfairly favor proprietary services."
Spotify CEO Daniel Ek and Deezer CEO Hans-Holger Albrecht were among the signatories to the letter, which was sent Monday to EU competition and business ministers, ahead of a scheduled meeting Thursday in Brussels. Travel websites, digital media companies and trade associations like the European Publishers Council and European Game Developers Foundation also signed the letter, which accused the tech giants of having "disproportionate bargaining power" and using their "privileged position to become gatekeepers to the digital economy."
Concern that U.S. tech companies have grown too big is a recurring theme for EU authorities, who last year slapped Google with a record 2.4 billion euros ($2.8 billion) fine for unfairly favoring its own online shopping recommendations in search results. More recently, EU competition authorities have opened preliminary investigation of Amazon's treatment of smaller merchants on its site.
Under the current proposals, the EU is seeking to introduce more transparency on how the platforms work with smaller businesses, including clarifying how they are ranked in search results and spelling out the reason for being suspended or terminated. The proposals also aim to make it easier to resolve disputes.
However, the group said the proposed regulation doesn't go far enough. "We stress that transparency alone will not rebalance the relationship between platforms and the businesses that depend on them," the letter said.
They complained that the tech giants favored their own services over third-party competitors using their platforms and forced businesses to use in-house billing systems that charge excessive fees.
Spotify, for example, has fought back against Apple's 30 percent commission on subscriptions processed through the iTunes billing service, urging listeners to instead pay directly through its website.
