One of my adopted "kids" I taught years ago picked this up at 17. He is 26, now. He "borrowed" the software to start (fair enough; it was a friend's license and not used at the same time), and didn't pay for a copy of Blender until he had a career path in mind and used Blender regularly.
A monthly thing makes no sense; just letting hobbyists dabble until they are in a place to pay used to be a lot more normal. They ought to make the entry for paying a bit less heartburn-inducing, though.
