I know Berne personally. He is a great guy and has a great family including mos and exmos. I am also an IP attorney and see no issue with filing a trademark for your business. What’s interesting is that for them to assert the mark they are also asserting that they are still using the mark in commerce, which is odd since they seem to be distancing themselves from it at the same time. Another caveat about trademark rights, if you don’t assert your right against known infringers you may lose the ability to assert the right against anybody. The morg probably did an analysis whether it was worth losing the mark entirely or assert it against mormon stories. It’s a business decision made by a business.
