TLDR: If you have a monopoly in a market, you can't use your position to get a heads up in another distinct market by bundling products together. Ex: Microsoft can't use their monopoly position in the OS market to get an advantage in browsers by bundling IE with Windows.
It's my understanding that this doesn't apply if you don't have a monopoly, and it also doesn't apply unless you're actually bundling the sale of multiple things together.

Doesn't seem to be relevant here IMO.
