it's about the licensing!
you surely must know that microsoft and bill gates were the biggest driving force behind the entire edifice of closed source right?
open source is not some new thing, in the old days there was a vibrant community of PUBLIC DOMAIN software, i used to go to my local amiga store to buy copies of Fred Fish disks and bring them home and play with all kinds of cool things
microsoft almost completely snuffed out open source coming into the late 90s and yes linux did help because it was a platform you could run GNU on
and i can't help but feel that rage at this decades of corrupt manipulation of the tech industry by microsoft, their promotion of object oriented programming, for one thing, a legacy that is still a plague on programming, and the fact that it's almost impossible for me to find a kernel version that supports my AMD Radeon RX 7800 XT video card, when it has a fully open source driver!!!!
oh but no problem intel garbage or nvidia
we still have a long way to go to rooting out the pernicious influence of copyright on our industry
