On a practical level, some of these have been unplayable online for months anyway.

The company tend to announce server shutdowns months in advance but while these games were only added to that list this month ( an archived page shows they weren't there on March 30th, at least), another list says they have already shut down. That means no online multiplayer or other features which rely on Ubi servers, though the rest should be fine. Ubisoft recently updated their kill list to announce they're ending online services for Rainbow Six Vegas, Rainbow Six Vegas 2, Rainbow Six: Lockdown, and Ghost Recon: Future Soldier from the vague effective date of '2021'. It especially stinks because Vegas 2 multiplayer has been broken for months, so players can't even give it a proper send-off. This is on top of the server shutdowns Ubi announced earlier this year, which included Far Cry 2 and Anno 1404.

The latest games condemned to lose online services include Rainbow Six Vegas 2 and Ghost Recon: Future Soldier.

As they do every so often, Ubisoft have announced they're ending online support for another round of games this year.
