Not necessarily. It was definitely bad if they want to become academics and needed to publish papers. But if they knew from the start what they were getting into and wanted to transition from physics to software development then it might not have been so bad (although there might have been a more optimal path).

A bad advisor wouldn't care what his students wanted, but a good advisor might still have students work on this kind of project as long as they were aware it wasn't going to help them get a tenure track position in the future. If they wanted to go work at a national lab doing HPC work and programing it might have been plenty ok for their career (This is what I am transitioning to now) or if they want to go work for a hedge fund or apple it might also be an okay option.
