Why? You already have to pay for these things, except you need to go look for them everywhere and find out how to import them and restore them from somewhere if you change machine. A marketplace for tooling is uber-valuable, and it's also an insane opportunity for creators who want to sell on these marketplaces.
The only thing I'm talking about is:
1. make the software free
2. incorporate a marketplace to find free or paid add-ons, brushes, effects, etc...
3. take a cut
