To me the title suggests the dev made the DLSS design intentionally worse, to generate controversy and now he is happy with the result.
The text actually explains that the devs just heard about the DLSS 5 alterations and were happy people loved the old design so much. Nothing controversial from him, not even intentional new designs.
Sounds like you got it right at first glance and I didn't. However, often these titles are intentionally misleading as to generate more outrage "you should be mad at the developer for creating controversies and being smug about the outcry". Not a fan of those manipulative tactics in modern journalism or whatever it calls itself currently.
