It seems you’re here to vent out rather than to seek help, which is fine. If you ever decide to ask for help, feel free to start a new post and add some relevant details so someone can help you.
No one here is claiming Netlify doesn’t have issues. But definitely not to a point of “hates dynamic sites and Next.js”. You could have landed on a new bug which would be good to fix, but currently we don’t know what it is, and we won’t know until you share some details.
