Well yes they do but the amount they would have got from me watching on crunchyroll or even buying non-aniplex blu rays would have been very insignificant. There is this argument constantly going on over at MAL. Somebody linked to this study that found that people who both pirate and watch things legally spend the most money. I know that I am not entitled to entertainment and I do feel kinda bad about it but I help as much as I can. Until recently, having a crunchyroll account would have been pointless because I didn't have any internet devices upstairs in my 2 bedroom house so that I can get away from 2 brothers XD. I do have a ps3 now (which I admit was £100 that could have been pumped into the anime industry) so I'll get crunchy this year and hope that the shows I actually like turn up there.
Without piracy though I would have never got into anime fully. There are quite a few shows on crunchyroll that I do quite like but also loads of stuff that I have 0 interest in. Without me pirating kara no kyoukai last year, I would have never really really got into anime and really wanted to buy MVM's boxset. I kept checking this website for updates and it made me really want to start collecting anime so I did with the small ammount of disposable income I get. Sure I shouldn't be consuming so much anime and I'm not going to get any more services outside of crunchy (netflix is really expensive, I wish there was a yearly rate) but I'm doing the best I can and my love of anime keeps growing.
