Isn't performing paid work activities with a keyboard application profiting from using the keyboard?

Are you selling and profiting from the keyboard software _as a product_? No, you're not.

Say I take the keyboard software/app _itself_, rebadge it as ohmykeyboard, then sell it for profit. I would be violating the license in that case.

Just typing with it and using it on a regular basis doesn't violate that part of the license.
