All other apps listed on the featured Apple Watch apps page are already available on the App Store, so Apple possibly removed eBay temporarily to avoid misleading customers. eBay remains a featured Apple Watch app on Apple's regional website for Canada in what is likely an oversight that should be addressed shortly.
"The world’s largest marketplace is now closer and more convenient than ever," the app description read on Apple's website, before the featured listing was removed today. "eBay for Apple Watch helps you stay on top of the auctions you’re watching. It can send outbid notices and other notifications directly to you, so you can react immediately."A few months ago, Apple removed award-winning healthy eating app The Whole Pantry from the App Store and its featured Apple Watch apps page amid allegations that its creator Belle Gibson faked having cancer to benefit her cause, accusations that later proved to be true. Gibson also failed to donate thousands of dollars collected during fundraisers to charities.
Update 11:45 AM Pacific: MacRumors spoke to eBay and confirmed that the eBay Apple Watch app has not been delayed or abandoned. It will be available in the coming weeks, but was removed from Apple's page due to the fact that it was the only app that wasn't yet available for download.
