When you use a linux distribution, you don’t look for a crack to pirate software. You look for freeware instead and there are plenty.
When you search video editing software on google, it will return only paid software or crippled fake freeware. That’s how they get to you.
Yes, Linux is far better than Windows and surely there will come a time when all software developers and brands will make Linux versions of their software. Companies like Adobe, Autodesk and others can easily shift their software on Linux but they intentionally won't do that because they won't get many users on Linux platform.
Even though they don't officially release their software for Linux but I'm quite sure that most of their servers and webservers are still hosted on Linux based operating systems. I think for video editors Windows is still a better option than Linux but for the ones who are concerned about security, Linux is the only safe operating system that they can choose.
