There seems to be a common misconception around some user forums. Maybe you recall this phrase:
RAM is there to be used.
This phrase is true within a particular context. It is used to let the operating system cache as much disk as possible into RAM, as RAM is significantly faster than hard disks.
However, within the context of a user-space application it is actually a fallacy. Some users (and even some developers) don’t know much about the inner workings of their computers, and use this phrase outside of its proper context. What is worse, sometimes they don’t even care much about RAM consumption. They don’t care about memory leaks, or think that if memory leaking occurs only once, it’s fine. Or they think garbage-collected frameworks or languages will take care of everything by magic. Without knowing, they end up using the aforementioned phrase as the equivalent of:
RAM is there to be wasted.
