Antifeatures
Antifeatures are a way to describe a particular practice made possible by locked down technologies. Antifeatures, as I describe them, are functionality (i.e., "features) that a technology developer will charge users not to include. You can read my short article on the topic published in the FSF bulletin in 2007 for a series of examples and a more in-depth description.
One thing I want to do is put together as large a collection of these antifeatures as possible to use in a talk, a paper, or maybe even a book!
List of Antifeatures
Panasonic Camera Batteries
Panasonic issued a firmware update with an antifeature which disabled any third party batteries.

Feel free to add your own ideas for antifeatures to this page so I can collect them and use them in an upcoming talk, paper, or maybe even a book!
You can use the following template:
