I meant free like the liberty that comes with free licenses, not free as in free beer (here free object ; ).
If this features is fully integrated in the SW design (a special donate button / flattr), why not.
But Shapeways doesn't get 20%. And it's better to pay all object + markups in one time.
Maybe we could use "capital gain" to remove the pejorative meaning.
No. But the SW system is quite opaque (hidden volume & markup : you never know how much you are giving to designer).
Letting people know some properties of the object (like volume), letting them download a model and tweak with it, getting them to be invested in the product creation, all of this is part of the education to 3D printing.
Well that's a personal questional (SW could allow both answers) but I truly think it should be, as in "free speech" again.
That doesn't mean people don't exchange money and that artists starve to death of course.
IMHO yes but my definition of art is very large.
I'm not forcing anyone (how could I ?)
