No, people hate it because it's a massive downgrade in UX, especially the wasm variant, just because backend devs don't want to use the right tools for the job. I'm fine with it in internal apps, but public facing apps using blazor would be horrible for the users, which is why it is thankfully very rare to see.
Javascript seems downright lightweight and unbloated compared to shipping an entire dot net runtime for a crud form app. For what it's worth, I don't care about turning off javaScript or even bloat in general, but this is extreme.
That's not how the right tool for the job works: the tool that results in the smallest bundle size and the most impressive web metrics is absolutely worthless if 99% of the value in what you're making is it existing and the creator of said tool doesn't feel like building out a SPA.
Of the tens of thousands of people who found my tool useful, the only people who ever complained where Hacker News users, and the tool simply would not exist if I had gone and wasted my time spinning up Next, realizing the app router is garbage, RSC has no place in most React apps, then going back to pages router, then rediscovering how awful NextAuth is, then...
Which is exactly how some of my otherwise interesting side projects die too.
