I want to know the answer to the following question:
What did the FSF feel that Apple was trying to monopolize on?
All the background I'm provided with is that "Apple's actions were criticized by some in the software community, including the Free Software Foundation (FSF), who felt Apple was trying to monopolize on GUIs in general, and boycotted GNU software for the Macintosh platform for seven years.". Is that enough to answer the question?
Answer: yes
