And even that was a fractured history. The Netscape to Mozilla release was heavily influenced by Netscape being bought by AOL followed by the Netscape team dumping a non functional browser (they ripped out a ton of code they didn’t own) on the open source world. People had to basically patch the stubs until it built and then rebuild from there. By the end, Mozilla barely resembled Netscape, but it did get the community finally building a serious open source option.
