Ask HN: Why is Microsoft pushing Edge so hard?

In the late 90's and early 2000's Internet Explore basically defined web standards. Once Microsoft decided on a new feature it became a strong candidate to be a new standard. It didn't always become a standard but developers were force to adapt their web pages to make sure they worked properly on IE. They want that power back.

If you don't use Edge they won't be able to track the web sites you visit so they can sell your data to advertisers.

Google does it too with Chrome. That's why if you visit Google sites with a non-Chrome browser they will push you to use Chrome.
