Sorry being thrifty
being thrifty is (in many instances) a good thing. Being dishonest is not. If your aim is educational you have the evals from Raisonance and Keil and, of course, SDCC.

These are provided for the benefit of students/amateurs etc and available for free.

If everyone copied Keil to everyone, the result would be a bankrupt Keil company, is that what you want?.

Anyhow, get off the fence and use what is legally free or pay for what cost money.
