This assumes the offer is legit. I seriously doubt even the most nefarious extension nonsense is actually going to bring in $20k/month. Even if there's millions of users.
That's exactly it. The "extension monetization" field is a product area fundamentally designed to scam its users. Clearly they're not going to shy away from scamming their suppliers. They just need to fool the authors into giving them control before taking payment, then they move on to the next mark.
Yeah, I've received plenty of similar offers over the years and I'd have been a lot more tempted if I actually believed any of the numbers.
That is nothing. I turned down the opportunity to inherit a Saudi Prince’s fortune for doing nothing (well just needed to pay his sons bail
bond or something)
It wouldn't be a long-term income anyways. Most likely Google would block the extension within weeks. So it's more like $20k total, not per month.
It's only $20k/month if (1) their number is truthful, and (2) Google doesn't ban your extension for serving malware.
