MyFonts is owned by Monotype, the big gargantuan soulless mega corp that is still profiting off typefaces designed by people that have been dead for over a century.

But if you look at independent font developers (who are just folks like you and me), most are perfectly reasonable in pricing and license constraints, and are happy to answer questions or even change the terms and conditions if this makes it easier for you to spend the $30 - $100. I don't think any of these are trying to be litigious, and they're certainly not ignorant.

(Though I understand that your misunderstanding of the web font licensing might make it look so!)

I never understand why so many font studios do this. I don't mind paying a fair price for a good font that a professional has designed, for the same reason I don't mind paying for a good book. But the terms for using it have to be sensible. They are now competing with some high quality fonts that are also comprehensive and professionally designed but free to use with few restrictions, so the licence needs to be simple with no sense of danger or I will walk away immediately. Some of these font developers seem to think they are the reincarnation of Elvis or something with the level of hassle they think people will go through to pay them money!
