Why am I seeing this message about 'esm-apps' on just one system?

I don't want to know about "Get more security updates through Ubuntu
Pro with 'esm-apps' enabled:", or at least I don't want to see that
message again every time I run 'apt upgrade'.

I already have all those packages installed on my system so what is it
suggesting anyway, are there 'security updates' for them that I'm not
getting for some reason?
