Big mistake to stir up a hornet's nest of political discussion. :)

But it's ok for customers? ;-)

Speex is not a product, it is a free codec (free as in speech, free as
in beer). Codecs and protocols are not products.

No one is forcing you to use anything. In fact if you are using Google
Talk and many other VoIP services, you may already be using Speex.
Would you use still HTTP if you knew that Tim Berners-Lee was a closet
anarchist or whatever? The technology stands and falls on its own
merits. The politics of its creator is immaterial. In fact, if you think
it's necessary to research the politics of a technology creator before
deciding to use that technology, you introduce a factor that is quite
outside usual capitalist reasoning, and (given the web of dependencies
involved in any modern technology) impossible to implement. So much for

We don't have a free market, we have a mixed economy.

In a completely free society based on the rule of law, yes. Our current
society is far from that ideal.

Nothing like insulting your potential supplier. Business 101?
Now I will proceed to show why Jean-Marc's message was not a left-wing
rant in the first place...

Politics? No, just noting how long it has taken a large, well-funded
company to produce a good-quality when they just could have used Speex
years ago. Seems rather wasteful, no?

Politics? No, just noting that all else being equal, open standards are
better than closed proprietary technologies. No vendor lock-in. No odd
changes that result in incompatibilities. Greater stability. Etc.

See above on vendor lock-in and incompatibilities.

Freedom is good. I guess that's politics. But a left-wing rant? I think
not. You can wrap yourself in the American flag with consumer freedom.

Yes, this one verges on politics. But it is true that Microsoft was
convicted of monopolistic practices both in America and in the EU.

Extensibility and flexibility are good technical features.

Aha, here is a political statement. :)
