To me, I consider the entirety of the experience with the plugin to begin the moment they click "install" for the plugin. From there, up to and including the quality of the plugin to perform its function(which has had hiccups), bugs in the plugin itself(which we've had 1 or 2 major security issues), and the ability to update along with how often the plugin is kept up to date. I don't even know how many threads and bug tickets have been made complaining about the plugin being out of date, nor how long it took to make the updated plugin available.
Just look at Opencloud. It's on 6.0 now, has been for more than 3 weeks, and the ticket was updated 3 weeks ago to a target version of "future". While I'm not bashing iX for their choices stuff being out of date does, in my book, decrease the quality of service appropriately. Especially when there's security fixes and features that you want to use that aren't available and are left waiting until some future date. Stuff set to "future" normally means "its not something that should be ignored, but its not on anyone's short term schedule yet".
For most people, each of those small parts has had various problems in and of themselves. So I don't consider the plugin a very good long-term service to use.
