Everyone who got tired of Ruby and Rails during its hype years has since moved on to various other technologies, now most of the people who are still working on Rails are the people who agree with its design choices, which explains the amount of praise it gets.

IMHO the major upsides of Rails were subsequently adopted by almost all major frameworks in other languages. It may not be sexy or make HN front page a lot, but Spring Boot definitely "caught on", for example.
