same for a lot of services you never use and are just dependencies of some software you dont use.
modem-manager is another example i just noticed just a while ago... because who doesnt have a 56k winmodem in his/her machine....
As for the rest that has little or nothing to do with performance, and foss drivers dont have lifetime support, may i remand you of the few old cpus and gpus that were dropped reciently?
further more, execute file attribute is as simple as some lines of code, what does that have to do with performance and general usability? repos might be a good point but freedom and drm have nothing to do with linux, that has to do with us, because be it linux, hurd or whatever, it us that decided we wont support drm and non F/OSS.
Efficiency and sustainability i dont think so, a we still struggle with buggy, low quality, with missing indispensable features software. And it's sustainable until the devs stop getting payed.
We are a lot better than before but we still miss a lot of stuff that is not hard at ll to fix.
We still have the dynamic vs static/semi-static linking dilemma and sandboxing stuff to alow per user application installation and incompatible applications to work in the same machine.
2 is DE dependant, i suppose kde for windows also has that. And there's also 3rd party apps to provide that on windows, there was one i dont remember that was free that was later bought by some company and made premiun, that provided the multi-workspace ability and even the 3D cube.
3 i agree, but sometimes it also does less than windows' gui
4,5,8,9,13,14 are also available on windows, not linux's alone
6,7 still need standardization (as in everyone using the same) and some features, I know everyone is free to use whatever they want in their distro but we'll never get anywhere like this. There's some stuff that needs to be addressed, including interdistro compatibility.
11 said it above.
15 never heard about it, will give it a look :P
