SecuROM was so dangerous that Microsoft outright banned it from running on Windows 10. And if you need an illustration of how stupid EA was for using it in Dragon Age II, they had already been sued for using it in Spore.
EA and BioWare claimed that the program included with the game wasn't SecuROM, just a different program that did all the same things. Which was like claiming you didn't key somebody's car because technically you used a knife, but it was blatantly false anyway. Savvy players found that Dragon Age II was indeed using files that came from SecuROM. Finally, Australian IT firm Reclaim Your Game published a lengthy report proving once and for all that EA had included the software without informing customers. EA executives promptly apologized and then never did anything bad again.
