Ah! I didn't know the specific reason as to why they stopped, but if they did it for this reason, I think they made the right choice, because it's hard to imitate Soraichi's humour by doing fillers!well gintama is another case, the anime stop because they don't have enough manga material to continue the series, rather than spamming filler for a year, they decided to stop the anime until they have enough manga material xd
OT: well considering bleach popularity in japan am not surprise they stop airing the anime, this also happen to d gray man and reborn, its sad but well it can't be helped
Hope Bleach continues, but then without fillers like Gintama!=DD
