The only viable (and vastly superior) alternative I think is running macOS, which would be prohibitively expensive for most organisations, especially schools.

Schools and government use GUI's for everything and Ubuntu's is just not good enough.

Ubuntu itself is good enough. If you mean GUI software providers different to the OS provider, then I agree. But not for the base OS.

Do you have any particular example explaining your opinion?
