It may be worth reading the whole paragraph of the blog you referenced...

> Figma isn't using true CRDTs though. CRDTs are designed for decentralized systems where there is no single central authority to decide what the final state should be. There is some unavoidable performance and memory overhead with doing this. Since Figma is centralized (our server is the central authority), we can simplify our system by removing this extra overhead and benefit from a faster and leaner implementation.

> It’s also worth noting that Figma's data structure isn't a single CRDT. Instead it's inspired by multiple separate CRDTs and uses them in combination to create the final data structure that represents a Figma document (described below).

So, it's multiple CRDTs, not just one. And they've made some optimizations on top, but that doesn't make it not a CRDT?



Nowhere does it say it's multiple CRDTs. It says "isn't a single CRDT" and that "it's inspired by multiple separate CRDTs." A bit confusing, I agree.

By the way, I work at Figma.
