Well, the game being slowly cracked and exploited somehow justifies lack of "safety". It's not like you're going to be hit by this tool abusers each time. For me, getting an 5IV egg without Instacheck alternatives has the same probability as running into a script kiddie on Random WiFi. If you agree to spend time on randomness with breeding, why don't you feel comfortable about the randomness more stacked in your favor to fight a fair battle?
And yes, when people exploit something and share it, instead of just hiding stuff to themselves, it actually gives other people ideas and starting points. Even if collateral damage happens, the end justifies the means.
