"if you install " a little bit" proprietary software on your system, you will
install more and more, and more."
this is not always the case
i had a few blobs (wifi and gpu) and minecraft
on my old system but i eventually got rid of them when i got a externel wifi
card and made a sacrifice with the gpu
but there were times when i was running ubuntu
the urge to play gta san Andreas was too strong for me
and i installed win 7 :(
so its ok i think to install a few blobs in the short term if it means
you will phase it out
but in the long term it just gets worse
