Are you suggesting that if somebody wanted to setup a basic scrapper, they should learn how to install python, use packages, figure out how the webpage is structured, and dig through the page source to figure out how to extract their data?
This project has a decent visual data picker, interface, etc. You could literally hand it to a non-programmer, and have them scraping comments off hacker news without any programming knowledge at all.
I get paid over 25$/hr professionally as a programmer. This project costs 40$ one time. I'm not saying it's worth the money, but all it has to do is save somebody 2 hours of time.
If you are a programmer then this project likely isn't for you.
