Because it was a comment written without having any context into how NYT handles their games. They assume something about massive monetization that would happen in the future, when the daily wordle will likely remain free forever, just like most other daily games that NYT has.
I do think there's a ton of nice things on the Internet. The FOSS community as a whole and Wikipedia are astounding in their civilization-transforming, anti-capitalistic effect on society. 20 years ago people paid Microsoft for the only half-decent productivity software around, Internet Explorer and freaking Encarta, for crying out loud. I don't think wordle is nearly close to the same level especially after getting bought.
