It's not wrong, just feels misleading. For me it's like Sublime text comes with a little tutorial with the title "Get started making apps", and only give an intro on making a hello world program in C++, to sell their product.
I don't get the problem with that either? Being an "artist", or "making apps" aren't hallowed titles. Are you treating it more like they're saying "You'll be a super successful musician" or "You'll be a multi-millionaire app maker"? Because I'm no seeing it like that.
I mean, is that wrong? Unless you stick to some elitist definition of artist, why is someone who plays with these samples to create something not being an artist?
