You get the same cost with closed source software and it's as old as software is. Try getting support for older versions of windows. Or DOS. MS walked away from that at some point as well. The benefit of open source software is that as long as the code is out there, somebody could take it upon themselves to fix things and share the results. You don't have that option with windows. And you only have that option with Dos because somebody created an OSS version of that; which is still being used by some to run stuff from last century. Windows is probably a bit more tricky.
