Would you prefer that someone who bought a shrink-wrapped copy of Windows XP at Best Buy 6 years ago suddenly discovers that their computer/browser stopped working as it should, simply because they chose not to upgrade?
Yes.
Would you be happy if Toyota came by and said they refused to fix your car since it was over 5 years old and your only way out was to upgrade?
That is standard practice in many industries. At some point, maybe not in 5 years but more like 7-10, you will bring your Toyota to the dealership and they'll explain that the part it needs is no longer available. Your options at that point include using aftermarket or salvaged parts, likely installed by an independent mechanic, or to get a new car. Life goes on.
