Useful for those who found themselves trapped on corporate Intranets based on MSIE-only apps.
Though IE8 and possibly IE9 work in Wine, yes, that's not what I meant. I meant that Microsoft was actively developing and supporting native ports of IE 3 through 5 on Solaris, HP-UX, Xenix, and maybe possibly Linux (I couldn't find evidence, but I remember seeing something about it.)
Where's the entrepreneurial spirit?
Mozilla are a non-profit. They came into existence because round about the year 2000, Microsoft had a monopoly in browsers and operating systems.
It's hard to express how extreme this was, if you didn't live through it. Basically, the rest of the IT industry was being strangled to death.
Two companies turned things round - Google and Apple. Both depended on, and encouraged, the open web. Google fundamentally built all their products on the web, and Apple relied on the web being open so that OSX and iOS could compete with Windows. (Would people really have brought the original iPhone if 99% of websites hadn't worked on it?)
The only reason the web was good enough to allow new companies like Google and Apple to thrive against Microsoft, was because of Firefox (which created Mozilla-the-non-profit).
Firefox was THE project. It was a non-profit project. It could not have been a for-profit project (well actually, someone like IBM or Sun or the like could have done it in a visionary way, but they didn't).
Firefox was basically run by volunteers, including a massive, complex marketing campaign, which involved not just geeks persuading their friends and parents to upgrade to Firefox, but also people asking website owners to make their websites work with web standards, and hence with Firefox (at the time many websites only worked on Internet Explorer).
So apedley, your criticism utterly misses the mark. Sometimes there are factors outside of the control of the entrepreneur. Microsoft's monopoly of the operating system and web browser was such a factor.
It can happen again. (Likely some kind of oligopoly of Apple and Google :)
I think we shall agree to disagree on this one :)
