Windows is bloated, always has been. Everytime you install an application you are installing another copy of all the libraries that program uses.

I think now that precompiled binaries for Linux systems are becoming more popular, they will also start to suffer from bloat as well. While the universal nature of SNAPS makes them useful, they will inherently take up a lot more space.

Of course the big difference between the two update systems currently is most Linux systems can update all their programs together. I have always found using repositories way better than hunting down updated packages in Windows or having to let each program individually update itself.
