Portability between different computers is only a secondary reason for the Z-machine. The most important reason is code size, making the largest possible game that can fit on a floppy disk.
Are you confusing Motorola Mobility with Motorola Solutions? The article is about Motorola Mobility, which makes cell phones. Motorola Solutions makes two-way radios and surveillance systems. They split in 2011.
Yes, thank you. I was not aware of that. The impression I had was that they were divisions or business units of the same corporate entity. That being said though, even though some are concerned about the Chinese connection of Motorola Mobility, I would have far more concern about Motorola Solutions being the partner considering that "the Chinese surveillance state" is far more remote than the tyrannical impulses of our domestic governments sitting on our necks.
Also, the original title is only 77 characters long, so there was no reason to change it. And the title should never be changed to something that misrepresents the article.
