You're saying that they breached their contract - he's just saying that the contract may not have been valid in the first place, thus it cannot be enforced/breached. We don't know if their contract was valid, that's up to the court(thats why this article is here).
It's still an incredibly asanine point for a general discussion because it's true of almost any contract. It's ajin to people who constantly use phrases like "in my opinion" in general conversations, it's already implied by context.
We'll see! Until then, revoking certificates is retaliation.
> you have a duty not to enter into them in the first place
This isn't how contract law works.
