If you can't see the difference between an up-charge WDW music event and this topic, I don't think I could explain it in a way that would satisfy you.
I agree, Disney could do more. But Disney's purpose for existing is not to propagate that message. The only reason this sky writing exists is to propagate a message - one that no one seems to actually receive. The point of the message being sky written is actually the opposite of the meaning of the values behind it. I understand because of the topic folks are being intentionally obtuse, but this is not a difficult concept.
Again, though - the entire thing is pointless because he's actually not espousing those values - his point is to say that if you visit WDW you do not have those values and therefore need to see the message, which if I did share those values would actually be quite offensive to me knowing the intent. But since his message is lost, the very folks who defend or support the skywriting don't even realize that it's actually being very critical of them in particular.
