"I actually think you're misinterpreting the reasoning here. Today JSON based APIs are quite a bit more powerful than RSS feeds and have become preferred by the vast majority of developers when building on the platforms you mentioned. This means that it's worth investing more time and energy into APIs over feeds. So I don't think it's that anyone is looking to actively remove feeds, rather they're just stagnating over time as more functionality is built into APIs." - David Recordon
