No software is always reliable, cheap, secure. Not even GNU+Linux in general, and not even free software.
However, if there's one thing that free software promises and has a chance to guarantee at long terms is: the respect to society's essential freedoms. To give you an idea, software that is licensed under a weak copyleft [permissive] license, or that is licensed under most lax [permissive] licenses allows for the redistributor to put a profit margin of 300% above the direct and allocated costs associated with the software, and when this happens, redistributors will say generally say: "Oh, it's free/libre software, so it has added value". At least the GPL tries to break this madness by requiring that the price of conveying the source of the work must-not be superior than the typical price of redistributing it on physical media, and this means: not applying profit margin upon the cost of conveying the source.
