My first response obviously is ‘neither’ but I realize that some of you need to use it for whatever reason, and need to make the choice between Adobe’s Flash and Microsoft’s Silverlight.
Both are very proprietary, however, I do recognize that Adobe has taken a few (baby) steps towards freedom. Sprinkled throughout Adobe.com are articles and such about Adobe’s latest free software (though they call it open source) projects, and I appreciate that.
Microsoft, on the other hand, needs no description when it comes to their stance on this issue.
Both extend support to GNU/Linux, though through a proprietary plug-in, however it should be mentioned that Adobe does this in-house while Novell had to get Microsoft to do this plug-in for GNU/Linux.
While I can’t speak on behalf of any efforts ongoing to make a free implementation of Silverlight, none of which I am aware of, we have been hard at work with Gnash, a free implementation of Flash Player. We’ve had some pretty good successes, and I’m hoping to more as we continue its development.
Plus, are you really asking me whether or not to use a Microsoft product?
