Developer Mike Dailly who posted videos from his early days working for DMA Design were taken down on copyright strikes. Dailly was the first employee at DMA Design. He created graphics engine for GTA which is pretty much the bedrock for the series' now-famous style.

Dailly said that Rockstar were "issuing copyright strikes to any GTA video they can find - including his prototype videos. So now they're trying to block all release of anyone's work on a game - and any old development footage."

Dailly's Twitter was also affected, forcing the removal of a link to download a 25-year-old GTA 2 design document.

DMA Design was acquired by Rockstar in 1998 and renamed Rockstar North. It was responsible for the creation of Grand Theft Auto, establishing the energy of a now quite long-lived series. Dailly's time at DMA Design also produced Lemmings. Dailly left Rockstar North shortly before the release of Grand Theft Auto 2 in 1999. 

The original Grand Theft Auto is not currently available for sale in any format, other than second-hand physical copies so it does look like Rock Start and Take Two are just being an arse. After all there are not many industries were you can be sued for showing off your work from 28 years ago. 

Dailly has removed all GTA dev stuff. Only direct examples of his work are left - work that was never used in GTA, but "inspired" parts of its evolution," he said.

Dailly is hacked off:  "Developers should always be allowed to show their work, especially works that are 28 years old"
