Someone came up to me at CES peddling outsourcing teams. I told him we just use Copilot.
If he had a good sense of humour he'd have replied "so do we"
Yeah there's your problem. Hiring a random person and giving them unlimited access to compute resources is a bold move to say the least. If you're gonna work on something like this, do it yourself or hire someone who you can really trust. That won't totally prevent it but it's better than rando Upwork contractor who will move on to the next gig
