It’s not AGPL though, and AGPL would have solved the underlying problem. GPL existed to force companies to release changes so “I can have it also”; and that’s a political view, the whole “free as in freedom”. Cloud wasn’t accounted for in this pre-centralised internet. 2001 (B2), is long before AGPLv3, but if you have the same ideology, that’s what you want. You built a thing using GPL based code, I want it also.
Freedom is never a given, it must be continually fought for or lost.
WPE says they use WordPress unmodified from the upstream source (which they contriubte(d)) to. The AGPL would not have changed anything in this dispute.
