It depends on how you define "tech" I guess. There are lots of companies I'd call tech companies that are either headquartered elsewhere or have branch offices elsewhere that include programmers.

Which of these don't have programming jobs at "tech" companies? Seattle (Microsoft and Amazon)? San Francisco isn't technically in the valley... Phoenix (GoDaddy)? Austin (Blizzard, a bunch of non-HQ offices like eBay, Google, Amazon, HP...)? San Antonio (Rackspace)? Armonk (IBM)? Malta, NY (Global Foundries)? Lockport, NY (Yahoo)? Amsterdam (Booking.com)? Houston (cPanel, Practice Insight, AlertLogic)? NYC (Fog Creek, regional offices for Google, Amazon, Facebook, etc)? Raleigh, NC (RedHat)? London (Canonical, Avanti Communications)? Portland (Puppet, some jobs for nVidia, Wacom, Mozilla...)? Boston / Cambridge ( Carbonite, Akamai, LogMeIn, Draft Kings, Wayfair, TripAdvisor ... with offices for Amazon, IBM, Google, Apple, Microsoft, Twitter, PayPal... )? Dallas / Fort Worth and their metro sprawl ( Texas Instruments, AT&T, MetroPCS, Ericsson, Intuit, Match.com, offices of ZTE, US headquarters of Blackberry ...)?

I think you and your siblings misunderstand. I meant, in the bimodal distribution of the post I was responding to, where do the programmers who work for these companies fall? I am one of them, after all.

Amazon and Microsoft are two off the top of my head.
