The few readers who were here in the mid 90s will have a very string deja-vu feeling right now: this is precisely what Java tried to do back then, when Windows had just won the "PC operating system war" against OS/2, and Java was proposed by Sun as an emergency exit: a platform where the operating system didn't matter at all; no wonder Microsoft did anything and everything to shoot it down! (Although Sun did a pretty good job itself, by not releasing it under a free license and hanging on to it way too tightly...).
Java programs needed a virtual machine that people had to download and install. It was a big download back then -- and a big install. There were several versions of virtual machines -- Sun's, Microsoft's, and a couple of GPL ones that never seemed to work 100% fine. They were all sort-of compatible one with another, but not quite. Desktop Java programs didn't tend to run well: they seemed to need phenomenal amounts of RAM, especially if you ran them for more than a couple of hours. Java libraries kept on changing -- AWT, then Swing -- and so did the various "editions". When Java finally matured and was released under the GPL, many years too late, it was already obsolete.
Wait, what about Silverlight?
Silverlight is a typical example of how Microsoft does things: release something; make it "sort of open"; allow a free implementation, but by turning a blind eye more than actually allowing it; make sure the Windows version of it has some specific Windows-specific features, and that crucial software will use those features. There you have it: Silverlight (or Moonlight).
They have no chance. They came late, and the world is largely ignoring it. They will try to push it as much as possible. However, the world has changed under their feet. Developers want to know that they can reach every user they can get to: a semi-proprietary tool won't do that.
Nice try though.
Maybe not. Right now, at the end of the tunnel there are thousands of online applications that are not free at all. They are sometimes (not always) free as in beer, and definitely not free software. Google Documents is not free software. Zoho is not free software. Basecamp is not free software (and in fact, you pay real money for the right to use it). The list goes on and on.
Maybe free software is shooting itself on the foot?
The counter-argument: is this really bad?
I am now going to make an argument that probably shouldn't belong here. It's an argument a very smart colleague of mine made once -- and it's stuck ever since.
Did we ever complain if the source code of a web site wasn't available? It's a weak argument, but it's a valid one never the less. To me, even more than the source code, there are two major components that need to be free:
The data. If I have data stored somewhere, and I can access it from several online applications, then that shouldn't be a problem. Unfortunately, that's not the case right now -- think about Google Documents, where all your files are sort-of locked in a Google world, a sort of file explorer that leaves a lot to be desired. The same applies to most of the other online applications. Yes, it's generally easy to import and export files, but that's just not really quite enough.
Format is free. This is another really important argument. Luckily, it looks like we managed. We have ODF -- Open Document Format. Most online and offline office suites today, free or non-free, support ODF. Microsoft Office "sort of" does, but that's the usual Microsoft story, nobody is surprised: files don't look right, importing is painful, and so on. So, my point is that if all of your documents are stored in an open, free format, then you shouldn't have a problem.
Note that once these conditions are true, free software alternatives to proprietary online programs are likely to pop up.
Back to the "world's CPU" argument
Whoever bet on it was definitely in the right place at the right time. Would you have ever imagined?
