SimonG: It's speaks volumes about the actual "restrictiveness" of always online DRM that a company can quietly shut it down and nobody notices it for month ...
If you were right and no one cares if games have always-online DRM, why then did Ubisoft decide to change it? Of course there is nothing saying "no one noticed", just because they didn't mention it specifically for you.
Not to mention many people who were still playing the games didn't necessarily even try to run such games offline, if they were expecting them to still need internet connection. I wouldn't try to run Diablo 3 offline, because I'd expect it needs to go online. That has nothing to do whether I wish my single-player games to be playable offline.
I certainly didn't notice the change with the Ubisoft games, simply because I have specifically made sure I don't buy such Ubisoft games which would require always-online DRM.
SimonG: And it still has a single online activation. Which pretty much renders the whole change moot. Either a PC has internet or it hasn't. It's not like anybody is still paying per minute ...
Yeah yeah, and everyone should be fine with streamed games too, because everyone is certainly connected to high-speed internet all the time while gaming... I just love these "I don't care about it, so no one else is allowed to care about it either"-arguments.
So I guess the Steam offline mode is completely irrelevant then too. Even for that certain GOGer who wanted to run his Steam games in offline mode for six months, while working abroad.
"Validation only during installation" is probably the least restrictive form of online DRM, but whether you are able to reach all the single-player content offline in future Ubisoft (F-2-P?) games is another thing.
