No sh1t, Sherlock.  Yes, they do. But, since they're a private organization, it's their business to decide if they will or won't, and their decision is the RIGHT decision since it's their private company.

If you and the subversive President can't respect that and the first amendment, that's YOUR problem, not theirs.  You whining about the platform and whether or not they're on the clock isn't the issue...that's just your whining and there's nothing logical about it. It's not "disrespectful" to anything.  

In fact, it's your whining which is disrespectful to the Constitution, the flag, and the anthem, as they represent the right for a citizen to exercise their rights within the laws of the land, which is what they're presently doing.

Follow along...pfft.  You've been consistently illogical about this whole issue.
