This essay is not about that. It's about people who attack a product/company/founder for reasons that are not about a product's functionality but are about their own issues.
This can be presumed to be be true of a critic who actively desires to see a founder's company "crash and burn" (leading to financial damage to them and their family if they have one), rather than just thinking it would be better for the founder to change their product or company direction.
For what it's worth, the personal bias I do have in this topic is in support of people like Suhail who are building products/ideas that seem crazy to most. The one I want to be working on, and that I earnestly believe could solve a lot of big problems over the long term, is one that even YC likely wouldn't fund/support, and that would certainly attract more resistance than Mighty. But that's for me to work through. I'm cool with where I'm at, but I’m going to keep having a soft spot for people like Suhail who spend years working on something that others think are crazy, as that’s the way the important problems (indeed, far bigger problems than slow websites) are going to be solved.
I believe this view (maybe pithily summarized as "people are corporations") is also the root of Graham's dumb article. If someone expends a lot of effort towards a bad idea and suffers "reputational damage" that's called consequences, not personal harm.
Meanwhile, I will continue hoping ~all of Peter Thiel's company's fail, which is not even a very controversial opinion on HN.
