Should they have to un-bundle Windows Explorer, Notepad, Photo Viewer, Control Panel, and all the other utilities as well, under the same logic? If not, why?
1) technically? yes, absolutely- apps like explorer or photo viewer should only use public APIs so other companies can make comparable apps on the OS with 90% market share
2) these are all OS utilities, not workplace apps - there's a big difference between Adobe/Microsoft Office/Google bundling their apps where there's a very clear, very powerful disincentive to compete vs something like explorer.
I think part of the problem is "what is an OS utility" and "what is an app". All your OS configuration could be done via a REST API, text files or some other well defined protocol. So you could have competing configuration apps that all help you manage your config in their own way and unbundle the control panel. Realistically looking at your average sparse linux distro shows just how "minimal" an OS can be, and even they bundle applications. Yet, I realistically don't thing consumers or the tech market at large would be assisted by a law mandating that all operating systems be as minimal as the linux kernel (no GNU/Linux, that's bundling!). And even if you did go that far, now we get into arguments over monolithic kernels and micro kernels.
sorry, no, that shouldn't be allowed either. as someone who's working on a cloud task scheduler, OS's should be forced to unbundle thread management. Linux needs to be banned in the EU until it doesn't come with a default thread manager.
