I'm surprised they have a Linux version. Ironically, it seems like you have to pay for the Linux version. I'm not actually that surprised that they offer a free version of the software with most of the functionality that most people need. The paid version of the software costs $945. That's definitely not something the average person who just wants to edit videos for fun can afford, but definitely something a professional can afford. They can get people used to their software by offering it for free. The few free version users who do go pro will likely consider their software over that of the competition because they're already used to it.
Usually I use FL Studio, but I've done lots of basic image editing with GIMP and I've made crosshair fonts with inkscape. Working with vector graphics and making a font with them for the first time was a pain in the ass, but it's so nice to see infinitely smooth curves and diagonal lines.
I'm not a great song writer, I can't write much beyond 16 bars, but I'm pretty happy with this piece I wrote years ago: https://soundcloud.com/noahadavis/ambition
