"It starts with author calling his users "fools" for not randomizing useragent"

He thought he was getting DDOS'd at first, and his attackers were using one useragent. In which case, they would have been fools.

"Then he realize "This is the biggest opportunity ever!"."

It __is__ a great opportunity! For the HN audience, a large influx of users is considered a great opportunity.

"They are just numbers for him, a viral mob that will do whatever their god tell them to do."

There seems to be a lot of negativity around this. I thought it was hilarious. Would there still be outrage if the users were American instead of Indian?

"His final solution - more lies and unethical behaviors"

I would hardly call it lies or unethical. 1. he isn't obligated to do anything 2. he ultimately delivered a usable product with a paid option to the service. Sounds like any other freemium app or in-app-purchase
