No. You have to establish copyright first. I am saying that their material doesn't meet the standard of what can be copyrighted.
Some things do not have any protection, or very little under intellectual property law. Just because you generated or made something doesn't mean that you can put it out there in public space and ask for protection under any of the intellectual property laws.
Copyright protection is only one part of intellectual property law and The WTS material does not meet the standard to be considered as qualifying for such protection.
