When I first read this, I thought this was meant to be a sarcastic statement on SystemD haters, but this is for real? I would assume this is all geared to scratching some kind of retro computing itch?
Being released in 1976, the Z80 architecture is well known and unencumbered by patents. It's also simple with fixed instruction timing, meaning it can be well tested, leaving few places for a back door to hide. The original hardware probably predates any surveillance programs (edit: and the silicon is being publicly reverse engineered by enthusiasts). There's a satisfying feeling of control, when in charge of a computer that is simple enough to understand in its entirety.
A Z80 won't be the fastest computer, but it might be useful for some tasks. Updates to the Z80, starting with FPGA cores, will be faster than the original, and might form a basis for enthusiasts to develop further. Let's face it, ARM's roots are in Z80 era processors.

For those unaware, the 6502 design was largely the product of two people: Chuck Peddle and Bill Mensch.
Chuck Peddle was an ex-Motorola guy that was on the 6800 team but was dissatisfied that Motorola was unwilling to bet on a much cheaper chip aimed at the mass market (the 6800 was around the $250 level before Peddle left; the 6502 debuted at $25 I believe).
Bill Mench was/is by pretty much all accounts a near super-human layout guy. At this time chips were still laid out without much, if any, computer assistance, and prototype turnaround was slow and expensive, so he was a major asset by cutting the number of prototypes needed (the legend - no idea if it is true - is that he had an amazing run of 9 or so designs that came back working on the first try; far simpler designs than these days of course, but to have any come back working on first try was uncommon).
Jack Tramiel at Commodore (who bought MOS) was always penny pinching, and so Mensch was able to retain rights to produce his own 6502 derivatives, and founded Western Design Centre, and have continued designing and selling related cores ever since.
* The architecture is already 32 bit.
* There are FPGA reimplementations, including a range of boards from different people, and open source designs (the Minimig) that people have produced working machines from.
* There's been a variety of work on producing more advanced versions of the cores, employing more modern design features.
* The M68k family has MMU support.
* There are Linux ports for M68k, as well as a number of other OS's.
Looking at his Google Plus ports, which includes various ancient hardware as well as a variety of old emulators, I think the retro appeal is more relevant.
"+retrotails prower I'm sure +Dirk Hohndel would like an Atari ST port but once you get past 286 there are better OS to run. For m68k you have to deal with the lack of segmentation or banking in most cases (so vfork not fork), but if you can do that then given you've usually got real DMA I would have thought 2.11BSD/RetroBSD a far far better place to start, or even ucLinux. Many of the 68K platforms are also blessed with other open but non-Unix OS's especially the Atari where basically all the underlying OS code you need is nowdays available in a free form (eg FreeMiNT/XaAes - which is even uses rpm)
Some of the key assumptions in UZI and thus in Fuzix really stop making sense if you have a 32bit system or you have good offloaded I/O. I'm not entirely sure those assumptions don't break down by 286 to be honest. However 286 protected mode is so wonderfully demented and feature filled it has to be done."
But as a fun retro project, on the other hand, UZI / Fuzix seems like an awesome thing to play with (though I'd prefer to see a C64/C128 version...)

Off topic but if anyone is ever in Cheltenham UK (or is prepared to pay postage) I have some old books I want to get rid of. http://imgur.com/AWV9HLn
Also, the M68k programming manuals should still be downloadable from FreeScale (what used to be Motorola's semiconductor division). At least they were when I looked for the last a year ago or so. They are wonderfully clear and detailed.
I like the idea of Minix, and that would be a good direction to move on, but the big companies who are contributing the majority[1] of the current Linux work are vested too much in Linux.
There are other projects targeting the same area, different approach though.

The beginning of the OP is obviously a joke.
This is a retro computing hobby project for 1970s era microprocessors. It's obviously not intended to be any kind of replacement for Linux or any other OS on modern computers.
