If they adopt open-source tool chains Xilinx & Altera would be signing their own death-warrants. The hardware would be reproduced by third parties (the open source code would contain all you need to know to produce the chips) and it would become a commodity like DRAM. Profit margins for the incumbent companies would go to zero and the users would profit immensely. Instead, FPGAs are sold to big entities like governments and big corps who can throw bodies at the crappy toolchains until they produce what they want.
