I clarified the point on Stripe a little. FWIW: Stripe is a.o. the company behind Sorbet[1], the Ruby type checker. A great contribution to the Ruby ecosystem.
From your examples, I only know Coinbase, and presumed they are primarily a Golang and React company, seen from their job vacancies [2].
Instacart, FlexPort and Gusto I had to look up. They are, indeed large, but not on my radar, because they are primarily US focused and -based. Thanks for correcting me!
I'm not sure if declining Google search activity for Rails is the best metric.
Common consensus seems to be that Google results for coding-related concerns have gotten worse and worse in recent years, and I agree with that consensus. Are people avoiding Google, or avoiding Rails? Probably a little of both, I'd guess.
I think a mature framework like Rails will also tend to have a greater disconnect between "people searching for help" and "people actually using it."

Me neither. That is why I wrote the post and included many more sources, stackoverflow insights, Tiobe, rubygems.org, github etc. I'm sorry If I did not put this forward more clearly. The initial graph was mostly a hook, and not so much proof, as I mentioned in the first paragraph.
> Stripe (2011)
Stipe doesn't use Rails at all. They use Ruby only.
>Discord and Mastodon
I assume you mean Discourse, the forum. Discord, the Chat App, uses Elixir + Rust
>Running Rails and started after 2010
Gusto (2012), Instacart (2012), Coinbase (2012), FlexPort (2014),
Although I agree with the overall thesis of the post. The sad state of things.
