Arduino is a platform, not a microcontroller. ESP32 is technically a microcontroller, but it's an SOC... which is not the kind that generally gets used for industrial applications in the field I'm in.
You shouldn't assume I get to choose the platform I'm working on. That's not how it works where I'm at, and if (when) I do get to choose, programming language is unlikely to be near the top of the list of criteria.
The statement you quoted is true of both of the examples you gave.
Also, you've deliberately chosen a specific interpretation of my statement in order to manufacture an argument that doesn't exist. You should probably avoid doing that in the future.
