With Canva, everyone can be an artist...except not everyone knows about the fundamentals of art which makes some art look better than others. That's the problem with offering graphics is that people prefer to try to build them themselves. They think it might be too much money to spend on images, or they can't convey what they want to others, so in the long run, it's better for them to just try to design it themselves.
I remember trying to design a logo once for someone and he said NO to gradients. I designed a few things and he said nevermind and that he got someone else to do it...and there was a gradient. Yeahhhhhhhhhhhhhhhhhhhhhhhh
