Actually, this isn't true. (Or at least wasn't a while back.) I used to work with a bunch of ex-V8 folks and they really despised third-party dependencies and didn't trust any code they didn't write. They used a few third-party libs but for them most part, they tried to own everything themselves.
.. can afford to suffer from not invented here syndrome
.. and are under _massive_ threat of people doing supply chain attacks compared to most other projects (as they end up running on nearly any desktop computer and half the phones out there)
this just isn't viable for most projects, not just resource/time investment wise, but also reinventing/writing everything isn't exactly good to reduce bugs if you haven't to reliably access to both resources _and_ expertise. Most companies have to live with having many very average developers, and very tight resource limits.
