Apple and Google have come under scrutiny by the UK antitrust body, the Competition and Markets Authority (CMA), for their dominance over the mobile browser market.
The CMA's report indicates that the market dominance of Apple's Safari and Google's Chrome is harming users and holding back innovation.
Apple's restrictive policies regarding mobile browsers, allowing only the use of WebKit engine, limit the features that can be supported.
The revenue-sharing agreement between Google and Apple, which discourages competition, is also criticized in the report.
