Dozens of companies have shown their support for the U.S. law curtailing the powers of large technology companies, and their position was made clear in the letter sent to members of the U.S. Congress on Monday.

Companies that support the law include Yelp, Sonos, DuckDuckGo and Spotify, which they describe as a “moderate and sensible bill aimed squarely at well-documented abuses by the very largest online platforms.”

Other signatories included the American Booksellers Association, the American Independent Business Alliance, the Institute for Local Self-Reliance and the Kelkoo Group.

The major opponents of the bill include Amazon.com, the Chamber of Commerce, NetChoice, the lobbying group that represents top tech companies, and others.

In his argument against the bill, Carl Szabo of NetChoice claimed the pressure being exerted to get a vote on the bill was a sign that it did not have enough support to pass.

The tech giants concerned have said that the bill will negatively impact popular consumer products such as Google Maps and Amazon Basics, and claimed that the bill will make it more difficult for companies to protect the security and privacy of their users.
