Erm... You trust too much in corporate mambojambo...

1) These clones implement an ISA (instruction set architecture)
2) You cannot copyright an ISA (the same as you cannot copyright a header file)
3) You can only copyright a specific implementation
4) You can patent certain ways how instructions work (see MIPS)

These clones are thus not any more dirty then their originals.
Only that the companies don't want you to use them. Which, from
their point of view is understandable: It takes time and money
to come up with a good ISA. It is something that you cannot easily
protect (see above). But the companies want you to buy _their_ chips,
not the ones from their competitor. Hence, if they cannot get rid
of those clones, they try to get as much FUD out as possible to ensure
that nobody is using those clones. If this clone is produced by a company,
the company will challange that FUD and get rid of it legally. If the
clone is done by a few guys in their free time and released as open source
(resp open hardware), then they will not have the time and money to battle
that FUD. and innocent people like you will fall for it.
