You know what? My pet peeve is referring to the "tech industry" as though that's a singular thing that makes some kind of sense to talk about. It's not. There's no such thing. It's at least 4 things.
1. Telecomunications (mostly ISPs)
2. IT professional services (design/development agencies, SaaS companies, and clouds)
3. Surveillance (they call themselves ad tech)
4. Semiconductor manufacturing
Sometimes entertainment gets mixed in, but that's its own thing
