Making your own tool suck/break/be-difficult when license-compatible patches are submitted to improve the program seems counter productive for everyone.
Don't worry, in a few years when iOS gets a major 3D-look visual upgrade it will trickle down to the desktop and things will be back to normal. In the meantime I've switched my macbook to dualboot Linux and only boot up MacOS when I have to use one of the programs not available for Linux.
Their basic argument is true but they completely ignore the fact that you can have two windows side by side on a wider screen monitor. Another issue they don't mention is some LCDs have shit viewing angles and if you are staring at them that way the colours differ from the middle to the ends. It sure would be nice if they brought back 4:3 though.
It seems like most systemd problems boil down to: shit this will take more than half an hour to understand, I'm a lazy admin and don't feel like learning something new.
