I think you're making strong points that what generates revenue for these places isn't always quality but social media hype / overly broad appeal etc... but objective quality is still a huge factor. Some restaurants may have a 2/5 star score because they're too innovative, but many have that 2/5 because they're simply serving bad food. If a place is serving burned/undercooked/expired food, I'd like them to feel like they need to address those issues.
