Back in the Relay Classic days, the Apollo client library was a lot easier to use and a lot less heavyweight than Relay. My team ripped out Relay and replaced it with Apollo early in development because we felt Relay was too confusing. Relay Modern may be better; I haven't used it.

They're also intending to make most of their money by promoting GraphQL as a tool, so low rates of adoption are an existential risk for their company, while Facebook only needs GraphQL as a PR and recruitment tool.

Ironically Relay Classic only needed a babel plugin, whilst Modern has a separate compiler you need to use. That said, the main issue with Relay is that it still has poor documentation, so it can't really compete with Apollo in that regard.

But I'm not going back to a world without data-masking at the component level, so Relay is the only choice for me right now (though I wish it wasn't).
