Again, "tech" != "technology" in this domain in my view. It's the double-great-gp or so that says it, but "tech" in my view leans towards companies with humungous software outreach and data ownership, so clearly FAANG but also Microsoft, Palantir, data warehouses, that's the kind of thing I put in this "tech" bucket. It's a type of company that probably knows more than it should about a lot of things.
And again, this isn't the "Wikipedia" definition (which itself has context-based caveats...), but my opinion and experiences involve this being the sphere of companies one calls a tech company today. I apologize for my inflammatory tone in the other comment and hope I have explained my point, even if you hold a different experience
