Android will routinely clear out cache as it ages or when other apps need more space. The developers don't need to worry about cache usage if the OS is handling it all for them. The problem is that all the apps get a quota so you can quickly run out of space on the device unless you either have a lot of internal storage or can move the gluttonous apps to an SD card. I keep social media apps on internal storage since I usually want things to load quickly but keep apps that cache movies or music on the SD card since that's fast enough.
