Anecdotal but I have a team of devs under me, cheating is definitely still a thing in industry. Some people copy other people’s work and claim it as their own and they are weak devs. I could teach them, but when it gets close to micromanaging I have to let them go due to poor performance.
Many of them don’t grow up. Be an adult. I hire people based on how teachable they are. Cheating cheapens that.
