Backdoor? Even if it isn't blatantly obvious - some autistic kid will notice a program runs 0.05 seconds slower and will work it out.
At the very least if you're going to be backdooring your code you might as well add "back door goes here" to your PR so we can easily cut it out when the hard fork happens without the backdoor included.
Wait that company still exists?? Huh TIL!
I thought the company died once people got the shits with them and stopped buying anything from them.
