I'm not defending it. It's a result of google's ranking system+ad system. All these descriptions are not for users to read, these are for google crawler to rank higher in search+to get more money from randomly placed ads. If you don't do this, chances are high your website will rank lower compared to someone that did this considering other factors are the same. I'm just saying that out of the all bad options, this option with a button is less bad, you skip all(most) unnecessary stuff with a button click
