If SLOBS is just a fork, then why is that a concern? Am I missing something here that will mean that the main OBS project suffers from this?
I think the only concern is taking attention away from an opensourse solution when they could get more funding/attention to keep it current. Though I doubt it will ever go away, since once you deal with a crash or something weird with SLOBS you immediately go back to OBS.
Its OBS on training wheels, shiny pay for more shiny training wheels.
