Right, that makes sense if you have sessions often. But, the thread started with automatic updates being bad for occasional users because they either have to waste energy keeping the machine on all the time to get updates in the background or have their mood cooled when they want to play but are forced to wait 30 minutes for updates.
Personally, I use Steam often but even then I get annoyed at updates. If I quit Steam, I sometimes have to wait for it to download Steam updates. Sure, it's not 30 minutes, but they happen when I want to play. I keep Steam open on my always-on machine and it annoys me. There's a reason I run manual updates on my computer on Fridays... then I don't get interrupted. Apps that auto update suuuck if you value your time.
