That's exactly what the problem is. The diffusion of responsibility makes it a decades-long problem and nobody has the responsibility or the power to fix it.

OK, so, why bother complaining about it? Use Linux if it does what you want, otherwise use macOS or Windows.

Because I don’t think it’s unreasonable to want:

* A desktop package that isn’t a vehicle for ads (like Windows and ChromeOS).

* A desktop package that doesn’t require you to write your own one-off scripts to work around stupid deficiencies (like GNU/Linux).

* A desktop package that doesn’t constantly throw away all its “legacy” and break a bunch of stuff (like Mac).

It’s indeed not unreasonable to want that, but there does not exist any incentive structure that would cause it to exist. It’s not the fault of some person or group of people doing something wrong; it’s simply a logical consequence of what Linux is.

A problem can’t be blamed on a single entity is still a problem, right? I think OP was just explaining the issue.
