Well, sure it is, and I’m sure they’ll get around to updating their plugin.
The issue is this:
If I do an update, I can back up my files and database prior – that’s what is recommended.
If WP updates automatically, there is no backup.
So here’s an actual situation where that caused a big problem (site not functional after update).
Is it really such a big deal to give end users the option of choosing automatic updates or not?
