I very much didn't intend to offend you, copy you or cause you to be upset.
That homepage design is based on what Udemy looked like before their update and that's why I felt okay to use it as a starting point.
That said, I'll update the homepage for the course today with a new design as a gesture of good faith.
I think the platform itself, not the homepage/sales page is what the people using coursify like. I suspect many of them won't even use that homepage. It's just a starting point.
Again I'm trying to make friends not enemies. Hope I didn't offend you.
Felix
Happy Easter.
