All of those are the same type of CPU, and all of them have words  
which are 8-bit multiples, and they can address memory and registers  
on sub-word boundaries.

For most programmers, the only difference is the ISA and the compiler  
hides the majority of that unless they go a little above and beyond  
the norm in learning their hardware.

For that matter, why should I constantly have to prove I am not a  
thief, and why should I be required to constantly expose my systems to  
security problems.  Why assume I have a network connection at all or  
that I want my end-user systems directly exposed to the net?

All of these and related assumptions are stupid and dangerous, and of  
course, how do I use my system when the remote system it depends on  
goes away?
