For this problem, the use of Google kernel by Edge browser is not infringing, because the kernel of Google Chrome browser is open source, namely Chromium. This means that anyone can freely use the Chromium kernel to build their own browser without permission or authorization from Google. Therefore, it is legal for Microsoft to choose to use the Chromium kernel to develop the Edge browser.

One advantage of using Google kernel is that it provides better compatibility and performance. Chromium kernel has been extensively tested and optimized, which can better support web standards and the latest Web technologies. This enables the Edge browser to provide a better user experience and be more compatible with modern websites and applications.

At the same time, using Google kernel also helps to reduce the cost of development and maintenance. By using the existing open source kernel, Microsoft can focus on improving the user interface and function of the browser without building a new kernel from scratch.

It should be noted that although Edge uses Google kernel, it is still Microsoft's own product with independent user interface and functions. This means that when users use the Edge browser, their data and privacy are still protected by Microsoft privacy policy and security measures.

Generally speaking, using Google kernel in Edge browser is not an infringement, but a legal and beneficial choice, which can provide users with better browsing experience and performance.
