i think this is valid, i think i will open source this or even make it free!

It is ok to charge money for things you make and charity toward the poor has more impact than charity toward developers.

In addition, using a credit card online is much much easier than using github. Particularly for non-developers.

My point is in the means of charging. I’d rather pay once and be done, than pay forever.

I think whenever possible, a one time fee is easier on users.

Subscriptions segment the market away from potential one time customers and toward potential repeat customers. Repeat customers are usually better because their incentives tend include your business staying in business so that the product remains available. Maybe this particular product isn’t for you. Or maybe it’s not ideal for you but still good enough. Or not. Everything isn’t for everyone.

Yes, exactly. It's rent-seeking in an intentional bid to distort the market and cause deadweight loss. It is inherently evil.

Everything isn’t for everyone, that’s true.

I want the world to have good products that are for lots of people.

Having lame things that are rent-seeking with no functional benefit is not good. Saying “it’s only for idiots, not for everyone” isn’t very constructive.

I’d rather people make products that are efficient and equally beneficial for creator and user. Not to exploit every drop of value from users that they can without making users quit.
