Luke,
Short answer: Yes, maybe.
Court cases on this subject go back a hundred years. A man by the name of George Eastman invented roll film but the camera had to be loaded into the camera in a dark room. His philosophy was that he could give the camera away but you had to buy the film and processing from him. The courts did not allow him to restrain trade in that manner. (BTW, you will not find that on Kodak's history site. See US vs. Eastman Kodak, 1915)
Bill Gates had a similar idea. 'Give' away his OS for $20 a copy as long as the manufacturer of the computer hardware preinstalled his OS on every box that left the factory. He soon had most of the world hooked. I remember shopping for computers in 1984 and hearing the plug for MS-DOS.
If you make a service agreement with Apple, you are bound by their rules. But, once someone buys an Apple device, they own the device, not Apple. Courts have limited how many millions and billions of Dollars George and Bill could make with their attempted monopolies.
While the US court cases will not control the outcome of a British court ruling, the information is instructive. Also, read the cases where Steve Jobs wanted to exclude Microsoft from making cheap imitations of his OS with Windows, even after Steve lifted the ideas from Xerox.
There are plenty of self righteous attorneys out there willing to work for self righteous inventors to protect monopolies. Then you have open source and the San Francisco Home Brew Club.
Your question is a little too deep for this forum so read up on your own or hire an attorney who has already done the reading. There is plenty of reading for everyone!
