The only reason I've had to replace them so far is that it becomes impossible to buy replacement blades and foil. So I have to buy a model that is only superficially different, instead of just replacing the expendables.
You can do what the article says and just buy a double bladed razor, more environmentally friendly because you don't get stuck in this trap, the disposable part is just steel, it's easily manufactured and not proprietary. Or, you can buy the disposable parts for your electric shaver with the shaver, keeping in mind the actual, working lifespan of the device. Or, you can use a straight razor and a strop, no disposable parts necessary.
In any case, whether you agree with me or not about this detail, it's vastly less use of throwaway plastics, less use of metal, less energy use from manufacturing and delivering all that stuff, and of course, way cheaper.
No packaging used up for all kinds of shaving soap or cream or other products, no packaging or plastic or metal used up to buy thousands of blades, etc.
