I look at startup employees as being very similar to investors; instead of investing money, you invest time. Most startup investments fail; the investors lose everything. You have to know that going in.
Nitpicking the instagram posts also seems pretty petty. We're criticizing the CEO for spending time with his family and walking around in the rain? People do stuff outside of work, even though there's work that they could theoretically be doing. Most people consider that healthy, and even CEOs that failed badly still deserve some recreational time. (It would be pretty cringey if the CEO looked up your Instagram account and posted a blog post like "why are you visiting your parents when there's still bugs open against your component!", right?)
(I take particular exception to the "Carson enjoys a climate-related disaster (#hurricanehenri) two days after announcing a severe reduction in force" caption. It's not like he willed the hurricane into existence, or could do anything to stop it. Why are we mad at him for climate change and random natural disasters? The dude is bad at being a CEO, but he's not God!)
