IANAL, but I find 2. weird, my first thought was that it obfuscation would give the opposing litigant an argument for willfulness potentially increasing patent damages.
i.e. it may reduce the total sum of patent damages across all potential cases by reducing the number that result in litigation, while increasing likelihood of increased damages for an unsuccessful defense.
Can't help but think 2. really seems to me a double edged sword.
Well, I know they do No 2 and it seems to work a bit. My guess is they never bring up that motivation. Just say they hid their design to stop Chinese copycats and delay hackers.
