I know of no one who has injured themselves rowing (on a machine or outside).

I'm not saying these things are death machines or anything, but the concept of adding essentially seated row to a rowing machine is fairly dangerous. Throwing an air damper up to 10 and ripping on it for a couple minutes will leave you quite sore the next morning but adding high weight can start pulling muscles or slipping discs.
E.g. almost all high-level swimmers have shoulder problems, but no one who just goes for a swim a few times a week is going to injure their shoulders. Almost all baseball players have ankle problems, but no one who plays baseball with friends after work is at risk of this.
The reason rowers get back problems is basically a combination of overuse, the asymmetric load-bearing motion of sweep, and underdeveloped antagonistic muscles. Given the device and the target market, none of these issues are really at play here.
In contrast or my cycling friends (which I took up after) have back problems, in particular the ones who started when young.
Mind you this was more than 20 years ago so maybe the training regime has changed.
