I kind of like that they manage to present their project there without bashing other projects, apart from the whole name and approach of course.

It's a bit difficult to confirm, but given the name and approach this project is probably a part of the suckless community (however big that is and who might be in it), and on their page there is http://suckless.org/philosophy and some other pages, that would explain what to expect from sbase. Granted, that is not very concrete.
