The obit reads as if it was written by two separate people. It reads like DM didn't start writing until "He was my father."
I don't think family needs to tell, is obligated to explain or tell outsiders anything about the death.
It is much easier to say nothing, talk all around the COD, say one would rather not speak about the cause. Lying about suicide is somewhat extreme and unnecessary.
If whomever wished not to explain to the EEs of the company, they should have just issued a statement that WM died and no further info would follow.
DM could arrange things and even invite guests as he pleased. That isn't even the point. The point is his dad had many who would have liked to attend, pay their respects etc., celebrate WM's life, and apparently from comments around the web, they didn't get to. That is odd IMO compared to the majority of deaths, funerals, receptions, etc. that happen everyday.
