How do you get your product in? Easy, release product for free so small time creators, experimenters get familiar. Those people go to work for professional studio, they request davinci since they know it better. Then company further optimizes by buying expensive intergrated hardware to better streamline production...
Its brilliant to see this nonobvious market oppportunity. Further you get extra street creds, as yt people will love your product just for the fact its so accessible (free).
Everybody except Grant Petty. I've definitely heard stories about an expletive-filled rant when Adobe discontinued their "buy once, own forever" products.
Both him and Doug (the other main co-founder) genuinely care more about making good-quality, affordable products than being worth an extra few hundred million.
