I did this. I helped build the Air Installer network. I truly regret it. If you look up that name, all you get is people worried that it installed viruses or malware (guess what... it did) and how to remove it. The other results you'll see include the owners trying to sell its virtues. As though it's anything other than a way to exploit unsuspecting internet users for money.

I was young and naive, and I didn't think we were using it for malicious purposes. It ended up being worse than I imagined in the end. I left on bad terms and felt like a complete fool. These days I hear adtech companies pay well - I didn't even get that. Just a genuine waste of life and career time.

I discourage as many developers as I can from going into adtech. I met the worst types of people in that industry.
