I’ve used Bing for a few years for the free rewards points and purchase rebates, and it has worked very well for me when it comes to normal searches including searches for software development. I very rarely have to turn to Google when trying to look something up, and as you mentioned, sometimes Google honestly gives me worse results. I will say however that I have found the image and video search on Bing to be significantly worse than Google’s (which I already have some issues with). Not sure about the other search types like shopping or news since I never use them.
I’m not sure why these comments are so negative so far. If I’m understanding the article correctly, it is an optional setting to automatically open the app as soon as it is done installing. The Play Store isn’t just installing and opening apps on its own.
