> In many countries free speech is a right regulated as basic first amendment laws.

That's definitely not true, please realise the whole free speech argument is useless outside the US. Anyway, I think you'll find it hard to get people interested with such an argument, even if it is an interesting way to put it.

But your first point - the argument about owning a product - is easy to understand and much more persuasive. That's why the John Deere DMCA thing got so much press, and also why I'm convinced that the downfall of the EULA will be because somebody tried to limit ownership of a physical product (and not software, which may or may not reap the benefits, but won't be the catalyst).
