I think the cynicism is related to cloudflares recent previous releases that were considered to be slop that significantly overpromised on its capabilities/completeness. Trust can take a long time to rebuild.

Throw in the the bragging about slop and cleanroom clones to avoid AGPL, the name and April 1st launch date, and maybe the high priority afforded to agent-friendly crypto payment infrastructure if anyone was paying attention. Maybe they prompted the marketing agent with "how can you get HN to loathe a product as innocuous as an open source headless CMS?"

Other than that, it seems it might be a half decent headless CMS, if the bit of WordPress you want is its interface, and not the number of plugins and devs and not being tied to Cloudflare's infrastructure.
