IE literally refused to implement standards, rendered broken dom elements, allowed for proprietary native extensions and had many different apis for them. They had 90% of the market share and no other viable platforms. This meant developers built things which exploited these broken features causing huge compatibility issues when they aren’t (every other browser).
A simple lack of features didn’t make IE... IE. Safari is a pain in the ass but it sure as fuck ain’t no internet explorer.
I think Chrome is propagating lazy developers who think everyone uses their browser. Which means things only work in Chrome and no where else. It’s not as bad as the IE situation yet and hopefully it won’t be with Firefox kicking ass again.
