Quote from Tulip website:
Ironstone and Tulip invite the Commodore community to join the official Commodore C64 web-portal. Currently there are about 300 commercial websites that use the name Commodore or Commodore 64 without having a license from Tulip. Tulip will not allow unauthorised use of the Commodore brand.
Yes Tulip , it makes perfect business sense to try and sue the very people you are trying to sell to, the commodore users/community.
They call this a retro revival?
I call it commercial suicide. :-o
