That's true if you think the market is SaaS upstarts like Bluesky and maybe less true if you think of the market in terms of who buys hardware. I remember early on at Matasano working for a house account, a major US corp that isn't a household name, and being shocked 2 years in when I finally had to do something in their data center (a FCIP appliance assessment) and seeing how much they'd spent on it. Look at everyone who runs (and wishes they weren't) z/OS today, or Oracle. There's more of them than I think a lot of HN people think.
One of the Bluesky team members posted about their requirements earlier this month, and why Oxide isn't a great fit for them at the moment:
