You seem to have several deeply misguided premises.

1. We don't know ARM knowingly shipped these chips although they were vulnerable. Bugs happen.

2. Even if this was the case, an individual can show, and ought to, show decency and empathy towards others.

3. This last comment of yours is a straw man and I doubt you are incapable of seeing this. You parent's argument was much more nuanced and elaborate than your rebuttal.
