For those of us of a certain age, the phrase "can't we all just get along" connects quite naturally to Rodney King. So if you heard it, or for some other reason wanted to use it in a written piece ...
There's likely more to Zeldman's personal struggles with respect to his health and other financial concerns than what he discloses (rightfully so). But at the same time, evoking the rhetoric of King during the Riots is indeed perplexing when measured against what Zeldman does speak about more openly: his commitment to the open web in light of the aforementioned drama. In this regard, as the kids say, "It's not that deep".
Edit: +++ "in light of the aforementioned drama"
