It's because Musk is commonly defended, and borderline worshiped across most of HN. The downfall of twitter is the perfect opportunity for a wake-up call. And that's why this type of comment is more and more visible.
Everything twitter reminds me of its early days when people argued we didn't need RSS anymore. How I mocked the platformists with the hypothetical. Had I told them exactly what is going on right now I wouldn't have believed it myself.
Maybe other social services will/should follow the example? I hear the new RSS spec will ban linking to other RSS feeds.
