Even though Spotify is a subscription-based streaming service, it also has a free, ad-supported version. The price you have to pay is not one that comes out of your wallet, but rather looking at (sometimes annoying) ads. Many users have employed ad-blockers to get rid of those ads. How many? About one percent of its user base, meaning around two million people, according to Spotify’s CFO Barry McCarthy.

Now the company has modified its Terms and Conditions of Use to prohibit users from employing methods that block advertisements. The wording is as follows:

circumventing or blocking advertisements in the Spotify Service, or creating or distributing tools designed to block advertisements in the Spotify Service

These new terms will come into effect as of March 1, 2019, and Spotify could go as far as banning, suspending or terminating accounts that are found to be in breach of the Terms, including but not limited to those referring to ad-blockers.
