Ubisoft has released many games that require constant Internet access the past decade and then just shutting off the servers making the game completely unplayable. This just happened to The Crew last month. This will happen to:
The Crew 2
The Crew Motorfest
Steep
Riders Republic
Star Trek Bridge Crew
Skull & Bones (A AAAA game)
Newer versions of Just Dance
Newer versions of Rocksmith
And more…
Pirating doesn’t solve the game being completely unplayable when UbiSoft decides to shut down the servers.
The Crew could be played all the way through as a single player game. It made no sense for a constant Internet connection. The Crew’s credit screen for the final version of the game lasts over 45 minutes. Thousands of employees across the entire world worked on that game and now it is just gone with only gameplay videos being the only record of existence.
If Ubisoft kept the crew (and others) on your account post-shutdown, people could create community servers much like they have for Titanfall and others.
Piracy allows software to be controlled by users, not publishers, in a way that if there was legitimate support for it people can still reverse engineer these games to support them.
Gran Turismo 4, for example, can only be modded and given online functionality through piracy (mods require a version of the game used as a beta test for some features so it wasn't widely sold).
Piracy isn't the only tool in maintaining discontinued games, but it's fundamental to people who may want to develop alternative servers for them.
Pirating doesn't solve it, but It fixes the problem at hand for now.
The next thing would be sth. Like the internet archive to legally archive it when ubisoft decides to delete it from their servers.
