WordPress.org has blocked WP Engine customers from updating and installing plugins and themes via WP Admin.
Something I wonder, is it possible to have 3rd party plugin registries, so unconnected to .org ?
That said, as a WP admin of a tiny commercial website, I find it distressing that someone else can influence the functionalities of my Website. I already didn't install Jetpack because I dislike the intrusiveness and, frankly, the spying by Autommatic which is enabled by this plugin on our revenues and commercial transactions. All this points toward a direction that is not pleasant.
