If you really want to be charitable, it could just be it benchmarks well with Js. Maybe cache hierarchy or instruction extensions like Arm v8.3

The "build our own chips" could be like when people call entire computer towers "CPUs" and really just mean build the infotainment boards how they like. HTML 5 gives them easy portability in the case they want to change things out.

Security would probably refer to embedding something like Chromium and taking advantage of their sandbox

And "data network instead of stuff just working" could mean something like local network RPC/REST over HTTPS instead of CAN which is much more general purpose

This is all a lot of stretching... but sometimes non-technical people try to very confidently regurgitate technical things they hear while filling in the gaps

Especially because they don't realize how small changes in terms have such outsized changes in meaning (hence the calling a computer tower a CPU)
