It really is a case of a guy who didn't do the research on rabbits and is blaming them for his mistakes.
Yes, rabbit will chew, dig and can be destructive. This can be dealt with by bunny proofing and supervision when they are out of the cage. If your rabbit is a very destructive one, you might need to set up a pen or a totally safe area for them.
Letting them breed like that is just irresponsible. It doesn't sound like he just found the litters, but rather knew the male was humping the female. That there were at least 3 litters is too much. The female passing away is unfortunate but not all that surprising considering she as probably fairly young and had 3 back to back litters.
Saying they are affectionate and boring is a lack of understanding rabbits. Rabbits are not affectionate like a dog or even a cat, they are affectionate like a rabbit. They can ask for petting and affection for you. Some will run around your legs or climb on you. Rabbits are also a prey species, so do act differently than dogs or cats who are predators. Comparing a rabbit to a dog or cat is unfair to the rabbit.
Rabbits do play, you just need to give them toys. They like tunnels, cardboard and some hard plastic toys. Some also like other things. Providing lots of toys can make them do more and be more active (and thus more interesting to watch), but also less destructive since they are kept busy playing. I don't know if this guy provided much in the way of toys, but I kind of doubt it.
He seems surprised that he has to clean them on a regular basis. I do realize that most pet stores seem to keep the cages very clean so a person might not know how much a rabbit may poop, but you have to realize they do need regular cleaning. The pee and poop issues he had could be due to having the rabbits intact and having a buck and doe. If they has a shared room, even if not out at the same time, they can mark the area.
All the supplies needed are no different that if you get a dog or a cat. While what you get is different, you still need to get stuff like bowls, a crate or cage, food, bedding, cleaning supplies and other supplies. When he got his cat(s) did he complain about having to get a litter box, litter, food and water dishes, toys and carrier and other supplies? Probably not, yet he complains about rabbits needed stuff. He should see what I have for my rabbits and what I may by on a regular basis just because I think they might like it.
Rabbits do need owners who know what they are getting into. Rabbit chew, poop and eat a fair bit.
Maybe I need to invite him over to see my destructive (not really), not affectionate (as they come up to the cage for pets and attention), dirty (I guess the litter boxes might be a bit dirty and they could be hay in the cage and a few stray poops), untrained (they don't come when called and it is hard to stop them on the agility course when they want to run), they are also not very playful (except for when they have toys and get to run around), there is also the issue of them attacking the other rabbits and dogs (my bonded pair sure hate each other, they groom all the time and Korr does try to steal Amelia's treats. The dogs are also afraid of the bunnies).
It is sad that he had a bad experience, but it also seems like he didn't put the effort into understanding rabbits and seeing them as rabbits and not just something to compare to a cat or dog.
