Most applications clog up the cache space on your device’s memory. You have to delete the cache manually which is not convenient. Fedilab is one of the few applications that has a self-cleaning cache function when exiting the application. Why don’t many other apps have a feature to disable caching or self-clear the cache?
It’s possible. In the YouTube application, this is really true, but in many others the cache is not deleted by itself.
Interesting, I would guess most developers trust the caching mechanisms they are using will perform well long term, and don’t consider that a user would want more control over the cache. Caching is inherently a performance feature, so it’s probably seen as essential to user experience rather than an option
From the QA perspective, I think most developers assume the cache mechanism will keep working the way it does on their device in their short development cycle, and don’t really consider whether it will eventually break, when applied to millions of different configurations for an extended time, with differing usage behaviors
