While I worked at Apple a directive came out forbidding developers from adding more RAM to their systems without express upper-management permission. The reason was that the experience on stock-ram supported systems was getting really bad and management wanted the developers to feel the pain (so they would fix it). Note: dedicated compiler boxes were exempted from this (but still required management sign-off).

A similar directive came out about that same time forcing all managers to use the baseline phones, and limiting the upgraded models to only testing fleets, for about the same reason.
