Well I know there are people who do not like libhybris as the manufactures then feel they have no reason to write drivers for glibc and they are closed and we cannot modify or update them. people like this:
""Things took a wrong turn a while back though. In an effort to create a
stopgap solution, Jolla developer Munk created libhybris, a wrapper
library which allows the usage of android drivers on top of glibc, and
thus on a normal linux installation. I find this hack pretty dangerous,
as it makes all vendors complacent, and it cements the android way of
working and the it makes binary drivers the default. Our biggest open
source hopes for mobile; Sailfish, Firefox-OS and Ubuntu-Phone Mir
readily embraced this way of working." http://www.osnews.com/thread?595445

However what could we realistically do without it? Can the community reverse engineer drivers and write them? Maybe but I haven't seen that completed on my N900 yet so I find it unlikely before the hardware becomes very outdated and people lose interest. Manufacturers won't do it unless there is marketshare and $$ IMHO.
I want open drivers but I am very thankful for Stskeep's work that allows us to have a chance at alternative systems on more hardware, I don't see another way.
