Back then the battle was over $100 C compilers. You likely haven't ever paid for a C compiler in your life, and I guarantee you that your life is better off for it.
If you want to make software that is valuable, you should compete for market share by doing it better than anyone else. Otherwise, your work kinda is worthless. Stallman noted this in the 1980s, acknowledging that the cost of manufacturing software is only limited by the cost of storing it on-disc and transmitting it over the internet. He was right.
I will enjoy my free compiler, thanks.
