Thanks Jack,
Actually I'm interested in:
We can make this license cover the end users of that product so that they won't need to get a license of their own
Because the banner-makers will be making money from their customers.
but you say...
" it wouldn't be fair, for example, if 1 developer builds a tool that lets thousands of people build custom GSAP animations via a GUI under a standard single-developer license".
Does that mean I would have to buy multiple dev licenses (one is 200.- yearly right?) if I want to sell my GUI?
Anyway if it's a special contract, could you please give me your email and I'll contact you.
