Both the European Union and the US government took Microsoft to court like 10 to 15 years ago and neither got satisfaction for Windows users over the "bundling" of software and the preferential treatment that MS gave their applications over competing software. The US got very little over their protracted court cases, where the EU did get a "small win" for the consumer. But those EU sanctions have ended and MS is back to the SOS (same old sh..). Would you have Mozilla "take action" by spend their funds which are used for operating expenses on a battle that they stand little chance of winning? If you think that "advertisement" is false advertising for Edge, how about starting a class action law suit with the Federal Trade Commission ''(the US consumer protection arm of the federal government)'' against Microsoft.
