IE’s problem was that it was too successful and Netscape couldn’t keep up. Further, MS had shorty coding practices so IE was deeply ingrained into Windows. But IE set a whole lot of standards and pushed the web forward. The one complaint with IE was that at some point it stagnated. This was unlikely due to malice on MS’s part and more likely because once again, MS’s shitty coding standards meant it just couldn’t improve. One way to know this is true is the fact that even after IE was surpassed and rapidly losing market share, MS wasn’t able to bring it up to speed with its competitors. It had to create an entirely new browser to even try and come close.
