I will say, I'm a big fan of your work at Authzed and SpiceDB, and while I think we probably don't see eye to eye on some topics like latency (e.g. I don't think same data-center is comparable to same node; or enough for realtime applications) ; I often recommend people to review and even use SpiceDB, it's my favorite open implementation of Google Zanzibar. I wouldn't call it a strawman at all in the context here - but rather a champion leading the charge.
I do think in the end of the day, there's much to be said about combining policy-as-code at the edge with graph in the cloud - my intention is to bridge the two (with an event-driven channel like https://github.com/permitio/opal)
Again, sorry if I didn't do a good enough job in portraying SpiceDB in the article, and I'd be happy to talk more about the subject.
