I can't say I agree. He could also summarize what the company said, thereby placing the accusation at company level. It's a blog, not a legal document.

Or, he could include the literal chat, yet blur the person's name and photo. I'd still object to that, but it's better.

I fail to detect why to make his point, he needs to reveal full identity details. I consider it a nuclear option, but I guess others see it as just "normal".

I tend to agree with your last bit. The guy has a strong moral compass, and clearly is a technical talent. I'd hire him based on that, minus this communication style.
