A campaign to keep DRM measures off the PlayStation 4 appears to have the ear of Sony.

PlayStation fans are hoping that the public backlash against rumoured Xbox One DRM measures will convince Sony to abandon any planned DRM on the PlayStation 4, and are letting Sony know their thoughts.

The lobbying effort began on NeoGAF, where readers were encouraged to tweet prominent Sony employees with the hashtags #PS4NoDRM and #PS4USEDGAMES.

Targets included Sony president of worldwide studios Shuhei Yoshida, head of hardware marketing John Koller, and senior vice president of PlayStation brand marketing Guy Longworth, along with some third-party developers.

Although it hasn’t provided answers regarding the DRM strategy for its upcoming console, Sony has acknowledged the effort.

“I love passionate #PlayStation Fans!!” tweeted Playstation software product development head Scott Rohde.

“This is why I love PlayStation fans- the passion bucket overflows,” tweeted Koller.

Neither Sony nor Microsoft has confirmed what their DRM strategy will be for their next consoles.
