Yes, but in a different way. I think it's better to pay for what you get. It's possible to put paid content online for free, this applies to also other marketplace sites like themeforest.net, but imho incentives for this are not strong enough.
True but as a buyer, I want exclusive rights over the digital content I buy, don't I?
I think so, but crypto-racism is real thing

There is so much hate in the space, especially between Bitcoin and its forks.
But that shouldn't affect your product haha I mean people just want to get paid regardless of what the payment method is. They will find a way to convert it into fiat/other coins.
