Now, there might be room for discussion about what exactly constitutes "air transportation service" and whether it exists outside of a part 121 or 135 operator, but for sure an ATP holder is not authorized to instruct "whenever he feels like it".

Actually, there is no room for discussion
This interpretation from the FAA's office of chief counsel removes all doubt that an ATP's instruction privileges are limited only to operations under Part 121 and 135.
And having been a Part 121 check airman, I can assure you with a great deal of confidence that any instruction which is required for pilot qualification under Part 135 or 121 may not be given by just any pilot who has an ATP, it must be given by a person specifically authorized by the certificate holders ops inspector to give flight instruction.
