Mozilla, the non-profit proprietor of the Firefox browser, has accused Google, Microsoft, and Apple of "self preferencing" and nudging consumers towards using their own browsers.
Examples of consumer harm stemming from this self-preferencing behavior include limited or frustrated choice, lower quality, lower innovation, poor privacy, and unfair contracts, according to Mozilla.
The report lands at a time when "self preferencing" remains a hot topic in the tech regulation space; the UKs competition watchdog has published a final report (opens in new tab) highlighting "substantial concerns" about the market dominance of Google and Apple.
These include inhibiting independent app discovery, citing how some companies bundle their respective browsers with their operating systems and set them as the operating system default in the prime home screen or dock position.
"For many people, this placement is sufficient and they will not see or pursue extra steps to discover alternatives," said the report.
