I recently did the same thing you did and wasn't particularly bothered by anything I saw. I sure didn't see the sports emphasis either. The only singular non-martial thing I saw were brutally sloppy shomen strikes by a brown belt I was working with. I think he was annoyed with the persnickity white belt he was working with. They didn't seem to mind if I showed up in style so maybe I'll wear a different one next time.
Seriously, if I read the ranks correctly, I wouldn't have had any major comparative gripes with what I've seen in other dojos. I think you got a bad batch.
As to maintaining the tradition. Nah, better off I don't go there.
