When you come in and right off the bat are condescending, haughty, and tone-deaf, as well as non-transparent, then don't be surprised if the internet is harsh.
This is not to say I condone in any way shape or form the hateful things being said about Pao or others. I do however understand the dynamic and see how they had a very active role in creating the reaction.
For example, consider if she had admitted her mistake and gasp! appeared human and asked for some patience while she learned the ropes. Imagine for a moment that instead, she didn't censor or remove the comments but relished the mistake, laughed at herself, posted a funny selfie and didn't try to hide it. Just a hypothetical scenario, that's all.
She would appear normal, human and worthy of empathy. But when she doubles down and erases it, censors and bans people and doesn't address it. Are you surprised that the worst elements see these qualities and judge her harshly as a non-symapthetic figure who holds massive power over them with opacity, arbitrariness and condescension?
Consider this analogy, if you don't know anything about bees and see a swarm on your tree branch, do you go apeshit and start screaming and swinging at the bees with a stick? and then go inside crying about how you are a 'victim' because the bees stung you hundreds of times?
Another approach would be to learn a bit about beekeeping or hire a beekeeper who would know what to do. They would come in, treat the bees with the due attention and care, give them a new nuc [1] as a home and then enjoy years of delicious honey.
An intelligent person would make their choice.
A person who is driven by a cocktail of incompetence, entitlement and playing the victim would also make their choice.

TL;DR reddit needs a 'bee whisperer'
