I don’t think there is any commercially available macropad that allows remapping without compiling. A custom macro with a controller that runs MicroPython though, like the Raspberry Pi Micro, can be modified by changing the source code, so no extra software needs to be installed. See this as an example https://blog.4dcu.be/diy/2021/04/05/Macropad.html
Could this just be journalistic framing to make you feel a certain way? Do you think any reasonable person hired by Google wouldn’t know that they could/would be fired for staging a protest in the cafeteria?
