I like how "I’m not sure if they realize it yet, but Tailscale seems to work extremely well for polycules." is thrown in, as if its usual for any company to know what a "polycule" is.
A romantic network, or a particular subset of relationships within a romantic network, whose members are closely connected. They can be intimate, familiar, romantic, or sexual in nature , but not limited to. The polycule created is unique to the people involved and the variations, they create.
It is specifically addressing the GPs statement "as if its usual for any company to know what a 'polycule' is."
It is usual for a large number of companies (and tech folks) to know what that means, but disproportionately so for the Bay area. The blog poster certainly works for a company I'd call Bay adjacent, so they wrote in a language familiar to them.
It has nothing to do with "only place that matters", but simply explaining that given the context of the writer, it's a high likelihood they assume general familiarity.
