This feels like a private which has reached the public shorn of the context that would be necessary to understand it. I use Wpengine and have enjoyed it. They have some aggressive upsells and you learn you can ignore them. Actually had no idea about revisions, hadn't used them before I hosted with Wpengine. I very much like using Wordpress and Wpengine has helped make it easy to do so. I'm sure they have some things to work put between them but I feel this needs more info. At a certain level it's open source software and if it isn't a trademark violation and is allowed by the license terms then Wordpress has only moral suasion to work with. Very happy with the work Wordpress has done to make an amazing ecosystem. If they need something from WPEngine to keep things going I think it's fair to ask and perhaps they did but we're a bit in the dark here.
