> I don't have the answer. Especially in the past, it seemed like a cost factor to keep up a modern browser (just ask Mozilla) if people might as well install anything else and still buy your OS and use your services. Microsoft ditched their own browser engine and the current version of edge is just using chromium, so it's cheap to maintain. Edge uses bing by default so Microsoft can serve you ads, and it has a shopping plugin built in which also probably generates revenue. They can also try to redirect people to other microsoft services whenever they want in the future.
