i think http://www.ietf.org/rfc/rfc3701.txt is pretty simple to understand:

"It is anticipated that under this phaseout plan the 6bone will cease
   to operate by June 6, 2006, with all 6bone prefixes fully reclaimed
   by the IANA."

This superseeds "your ISP" or any other claims.
(as long as IANA reclaims them by then :-)

They are no longer valid, so they are considered bogon.

That's a totally different story.
IPv4 Prefixes are not allocated/assigned as TEST Prefixes.

6Bone 3FFE::/16 Space always was a Test only.

See http://www.ietf.org/rfc/rfc2471.txt

"This document describes an allocation plan for IPv6 addresses to be
   used in testing IPv6 prototype software.  These addresses are
   temporary and will be reclaimed in the future.  Any IPv6 system using
   these addresses will have to renumber at some time in the future.
   These addresses will not to be routable in the Internet other than
   for IPv6 testing."

So you were fully aware that those addresses would be reclaimed at some
time from the beginning.
