An investigation by Reclaim Your Game reveals that the new version of The Sims 2 Ultimate Collection contains SecuROM, the notorious DRM. But the worst part is the fact that, while EA was giving away the game for free (because it is ending support for it) to anyone with an Origin account, it didn't bother telling anyone that the game contained this DRM scheme.
Ultimately Reclaim Your Game found that EA had put SecuROM Version 07.40.0009 in the free The Sims 2 Ultimate Collection.
You can find out all the details by visiting Reclaim Your Game and checking out screencaps and other data that confirms that EA snuck this DRM into the game without telling customers.
For those who have already installed it and the Origin client, Reclaim Your Game also offers some handy dandy instructions on how to get it all off your PC.
