Documented cause
Google Reader launched in 2005 and became the definitive RSS reader — the infrastructure layer that powered how journalists, bloggers, and information professionals consumed the web. By 2013, despite 'declining usage,' Google Reader had millions of daily active and passionate users, served as the backbone for dozens of third-party apps (Feedly, Flipboard, Reeder), and was considered essential infrastructure for the independent web. Google announced its closure in March 2013, citing declining usage. 150,000+ people signed petitions; the tech community reacted with unusual anger. The closure was widely attributed to Google's strategy of consolidating social discovery into Google+. Google Reader shut down July 1, 2013. Google+ shut down for consumers in April 2019.
Lesson
“When a platform product is infrastructure for other developers (Reader powered dozens of apps), its closure has ecosystem externalities that extend far beyond the immediate users. Treat developer-dependent products differently from consumer products when making shutdown decisions.”
