You do understand that finding some rare examples will not actually proof the fact that free software lacks the same level of features for the professional world.
Maybe you will also claim that some top world gamers play games on Linux? Finding some unique cases
is always possible. But good luck trying to convince professional DJs (an industry that is closer to me) use
free software for their mixing and production, for example LMMS instead of Fruity Loops.
Or maybe you are those who claim that GIMP can be a full Photoshop replacement?
Luckily good content creators stick to the real thing, which is actually to create good content, instead of
following some flawed ideas that all software in the world should be free and open source.
