Anyone can do a APT GET and install a OSS stack or use Synaptics. But just having root permission doesnt mean you should. root provides lot of rights and powers and brings great responsibilities.
Every Stack has its own issues and problems which has to be resolved. Every stack also had lot of exposed interfaces which need to be secured. Until you have worked on that stack for couple of years the nuances of each is not clear. Ask any word user or a excel power user and he shall tell you that he/use uses only 5% of the power of the excel and doesnt know how to secure his document.
We offer hardened kernels of different open source stacks. Please feel free to check out different stacks here and do a 1-click deployment of each at Azure or AWS or ask us for on premise deployments.
