Stripe, AirBnB, Instacart, Zendesk, Kickstarter, Mastodon, and if I remember right Coinbase was originally Rails as well.

Many if not all of these companies are, to my knowledge, companies like Github which might still have some legacy parts of their system running Ruby, but aren't building significant new code in Ruby; and if they do have Ruby, are trying to reduce its prevalence in their system.

You're badly misinformed (or are intentionally spreading misinformation).

Your claim would have more standing if 1) it made sense vs. the news and recent yearslong turn away from Ruby development, and 2) if you included any sources or information other than "nuh uh"

'Download Github and look at the code'?

I can vouch for at least one of those companies especially if we go by the "trying" bit of the GP.

Square was originally a single RoR monolith. We spent a decade burning it to the ground with a Java and Go microservice architecture.

Some product surface area remains Ruby, but Ruby was chased away by most teams.

Square brought in a lot of Xooglers over the years to lead the transition, so you see a lot of Google tech: protobufs, gRPCs, at one point a pre-Kubernetes Borg clone, etc.

GitLab too: https://gitlab.com/gitlab-org/gitlab

Twitter also

Twitter famously eliminated as much ruby as practical from their codebase.

Had to kill the failwhale.
