His biggest beef with WP Engine is that their code is "bastardized" (???), because it doesn't enable revisions by default for their websites. That's one of the dumbest arguments I've heard. He's trying to convince us that only WP Engine is bad - and all other WP hosting companies are supposedly good.
Yep, it sounds like he is jealous/envious that they are making more off of WordPress hosting than Automattic. WordPress being open source makes this even more ridiculous, because he's complaining about modifications to open source software.
Yeah, I expected something more serious (like tracking usage analytics, scrapping data for some content generator or etc.) but it seems like the real problem is a minor function that {a lot} of users don't even know about?
