It's understandable when you see that the ethos is to have software that represents the user in charge of the rendering, rather than centralizing it all on the server. There is a major difference between common "app store apps" or hostile javascript bundled with websites, versus software that's been written to work in the user's interest. However as they use similar delivery methods, it's understandable that it takes a minute to think through and revisit your assumptions that have lead to being default anti- javascript or app.
