On release day, last year, I bought the highest license option of GravityView, now only 6 months later, all free.

Do I feel screwed now? Yes, to some extent...!

Ok, I still have access to all extensions. But I really wonder whether such spontaneous changes in the business model are really good in the end? I have my doubts here.

You read an interview with Matt preaching his ideology and then you turn your business model the next day.

Does that really reveal sustainable business models before or after the turn.

I still have my doubts. Not all trends seem to be good.

I totally get where Matt is coming from, but that doesn't mean that he is always right. He follows his ideology and he's a really smart and clever guy. However, his "attack" on Gravity Forms is unnecessary IMHO. The Gravity Forms guys know their business and if they ever will change their business model they won't do it because of a Matt interview.
