According to Google Trends, during the past few years, there has been nothing but a few minor bumps that faded away as quickly as they came. I love RSS because i do not have to scroll through dozens of different news sites all day and i would love it to return.
EDIT: Typical case of people only reading the headline. I was asking why people are hyped over something that did NOT happen.
The reason why RSS didn't become popular was because content creators didn't know how to monetize them while still having to pay for hosting fees.
Social media built walled gardens that could drive traffic to certain content creators if it was in the social media company's best interest. Content creators moved to social media since the carrot was too much to resist.
