Perception of software development is often confused from many people, so let's extend the metaphor to other fields, showing what would happen if this prohibition would be applied there:
- you're not allowed to edit images that will be displayed by Apple products with Photoshop (ops, Adobe). You shall use the iPencil instead and scan your drawings in a iJpeg, which is like a normal Jpeg but costs a dollar a piece.
- you're not allowed to write your PDF files displayed on Apple products with OpenOffice.org and export them in this format. You must use iWork (this one really exists.)
- you're not allowed to play musical instruments to produce songs that will be stored on the iPod or similar products. You must use GarageBand instead.
Of course I will continue not buying anything from Apple.
