As a former Rails dev, my two cents is that the language keeps breaking.
The small changes in 2.7 were understandable, but quiet a few gems that I used broke in 2.4, and in 2.5. It was a pain to fix, some were never updated.
Much how people complain that changing strings in Python 2->3 hurt adoption; we have had breaking changes that can break gems almost every release.
Ruby is a great language, but Python is so much less stressful, easier to find working libraries, and easier to find jobs. The last reason is likely because of the first two.
It is fine to add things, but when you keep changing the language and breaking things; people hesitate to write software in it. There is a reason the Linux kernel has a rule about (almost) never breaking user-space.
