Third Party RAM a no no?

RAM is on my mind it seems, and I'm not the only one. Dori Smith, beloved Mac author, has had a run in with Applecare.
She was experiencing some problems with her Powerbook and sent it off to Apple, as one does.

It came back right as rain, but with the warranty voided. What foul thing did Dori do to her Powerbook to deserve such treatment? Why, she installed non-Apple third party RAM. How could she?

The lesson that we have learned from this? When sending your Apple products to be serviced by Apple make sure you remove any and all third party RAM.

Apple, if you criminalize third party RAM only criminals will have third party RAM.
