No sir, the point was not the duration of support offered, but the concept of what support entails. In this particular example, just like you wouldn't expect a manufacturer to continue supplying spare parts for unsupported models, you wouldn't expect a software company to continue supplying outdated content for unsupported versions.
And before anyone brings up the "but they work perfectly fine!" argument for the umpteenth time, no, this has nothing to do with how they still work otherwise we can argue, "but N3V, TB 1.3 assets still work, why are you not supporting Trainz SP3?"
Yea, you can still find parts for your Apple II, but I'll bet a dollar you didn't buy those parts from Apple themselves.
