NTT's Violations against GPL

The facts I learned from the experiences of these days are:
NTT's Router ( RT-200KI ) contains GPL'd code in it.
And the users are not informed these facts, no GPL licence texts, no source codes, no pointer to the source codes are included.
1) NTT violates GPL beacause their router RT-200KI contains linux which is distributed under the GPL.
2) NTT violates GPL beacause their router RT-200KI contains BusyBox which is distributed under the GPL.
3) NTT violates eCos lincence (aka. GPL) beacause their router RT-200KI contains RedBoot which is distributed under the eCos licence.
4) NTT violates GPL beacause their router RT-200KI contains iptables which is distributed under the GPL.
5) NTT violates GPL beacause their router RT-200KI contains wget which is distributed under the GPL and its variant wget19.

The C library used may be GPL'd ( I don't know what libraries they uses. Their VoIP driver dynamically links to the library named libc.so.6, but it is realy a symbolic link to libc-2.2.5.so. It looks like some kind of glibc compatible another library. )

Aside from the GPL violations of NTT, NTT made a backdoor in its VoIP Router, and they can do what they want to do even in case of the user explicitely inhibit to do it.
I think NTT is violating not only GPL but also japanese 'Unauthorized Computer Access Law' .
