Bundling IE may have gotten more people to give it a try, but it didn't force those people to continue using IE. It didn't force them to keep using IE for years and years, in many cases.
Most people, including a great many former Netscape users, simply chose to keep on using IE because it offered (and still offers) a superior web browsing experience compared to its competitors.
