The author does point this out, but it might not be clear to everyone...
"Games and applications using either hardware accelerated Stage3D or domain memory individually do NOT require a premium features license."
So if you're just using Stage3D you're fine.

"Net revenue is calculated as revenue after taxes, payment processing fees, and social network platform fees are subtracted."
Personally I don't think taking a percentage of sales is a bad thing considering the R&D that Adobe have continued to invest in Flash. Having said that I think 9% is a ridiculously high percentage.
