According to the law, the best course of action is not to break the law to prove you don't like the law. While the Terms of Service are not the law, you agree to follow them when signing up and the terms didn't change after Epic signed up.

Practically, you may be correct that this is the most expedient way to try to fix the problem but you can get burned as Epic has in the short term with a sharp drop in revenue as Apple & Google have both booted them and may refuse to work with them in the future.
