So why expect the library for free then? Saying open source is not an option but not being willing to pay for the licencing cost of the "commercial" Version is quite hypocritical no?
Not at all hypocritical. The people who authored the code release most of it under LGPL, the intention of which is to allow closed-source dynamic linking against the LGPL'd library. I didn't decide this. The users didn't decide this. The people who actually wrote the code decided this.
But people still complain that using it for free is too restrictive and want static linking and freedom to modify the sources and not share the changes, all for free.
