After a years-long investigation, the European Commission levied a fine against Apple of €1.8 billion — about $1.95 billion — for “abusing its dominant position on the market for the distribution of music streaming apps” to iPhone and iPad users. The EU said Monday its investigation into Apple found that Apple applied restrictions on app developers preventing them from informing iOS users about alternative and cheaper music subscription services available outside of the app, which is illegal under EU antitrust rules.
