We can mock daybreak and all but there just doesn't seem to be a universe where this lawsuit itself is wrong. Even when lines of it are comical. There ARE going to be people who skip the usual tlp cycling because a better emu is out, even if 99% of the problem with fangbreaker was its own ruleset. The emu is stealing ip and profiting off it.
Most importantly though, NOT taking action is an action. If daybreak ignored this, they would be weakened in their ability to litigate in the futute because of it. Thjs big defense is very likely to be this logic - they allowed so many other emus and even compromised with hackers.
The emulators delved to greedily and too deep.
