Any device that its resources are assigned by software could have been designed to make a wrong use of them for several reasons. If the device has for instance 10 rooms, and they are all occupied, it's not a causality that the next period another device appears in the market with 20 free rooms and so on.
It's really easy to observe how operating systems are by rule always increasing their system requirements since the start of the computer age. A company could try to excuse itself making different statements about ease of use, speed (cache), or another similar arguments. Although, there are other available methods to achieve the same ease of use and speed; for instance with configuration assistants, or a more complex handler for applications, more optimization, etc...
A good example is Android 2.3, as it's usually caching almost every recently opened application, and persists reopening them, finally consuming great quantities of random access memory. The displayed reason is more speed if the user launches again the application. Come on... having hundreds of megabytes of RAM occupied for a potential application start-up that most of the time is under a second! There's no option (try Google Search for “disable cached applications android 2.3”) to configure this cache policy, and thanks to this, the mobile phone has more resources wasted, consumes more battery and gets slower giving a worse user experience.
Windows OS usually has dozens of services —executable files, a curious alias of common programs— running with a high chance of never being used by users in their entire life. The RAM consumption is higher with any update, and more lights turned on “just in case”.
From some point of view, a company usually has deep interest in making revenue and the past history is rich in cases of some of them making illicit movements. These companies did conceive plans to play unfair and fortunately there was legislation for creating limits, useful to everyone.
As RAM or another electronic component of course need electricity to run, with behaviors based in creating higher consumption to force new acquisitions of updated hardware, the result is a vast amount of energy resources wasted because the user base is up to billions. Another great issue to mention is electronic hardware waste and the illusion of recycling. For that reason, counting the problem of pollution and resource devastation, it's required to create awareness by analysis and therefore social response and government rejection toward this kind of acts that don't consider the environment nor the users' quality of life.
