* Low Ratings: The English dub of Bleach was never a huge ratings success, and its ratings started to decline significantly after the initial seasons.
* Production Costs: Dubbing anime is expensive, and the cost of producing English episodes became increasingly difficult to justify with declining viewership.
* Focus on New Projects: The English dub of Bleach was part of a licensing agreement with Viz Media, who were focusing on other projects at the time.
While it's possible some fans in certain regions may have experienced a stoppage of English episodes at episode 282 due to local licensing arrangements or distribution decisions, the main reason the English dub ended was the factors outlined above.
Keep in mind that the anime continued airing in Japanese until episode 366, but was not dubbed into English beyond that point.
