ChatGPT mobile app uninstalls surged 295% in a single day on February 28, 2026, after OpenAI signed a deal to deploy its models on the Pentagon’s classified network. One-star App Store reviews spiked 775%. By mid-March, the #QuitGPT movement reported 2.5 million users who had cancelled subscriptions, deleted the app, or signed boycott pledges at quitgpt.org.
What Triggered the Exodus
The timeline is precise. On February 28, Defense Secretary Pete Hegseth warned Anthropic CEO Dario Amodei that refusing the same Pentagon contract would result in contract termination and a “national security risk” label. Amodei refused publicly. Hours later, OpenAI signed the deal. The contrast — one AI company choosing ethics over revenue, the other choosing revenue — gave users a binary choice and millions made it.
Anthropic’s Claude shot to #1 on Apple’s App Store for the first time, dethroning ChatGPT. Reddit and X filled with migration guides. The boycott was not abstract protest — it was measurable platform switching at scale.
Altman’s Damage Control
On March 3, Sam Altman published what he called an internal memo on X. He described his own deal as “opportunistic and sloppy” and said he “shouldn’t have rushed” to announce it on a Friday. OpenAI would amend the contract to ban domestic surveillance of U.S. persons and prohibit NSA use of its models.
The concessions came after the damage. Protesters gathered outside OpenAI’s San Francisco headquarters the same day. The speed of Altman’s reversal — five days from signing to publicly calling his own deal sloppy — suggests the user exodus hit harder than OpenAI’s internal projections anticipated.
Did It Actually Dent OpenAI?
OpenAI still reached $25 billion in annualized revenue by the end of February 2026. The 2.5 million departures represent roughly 1-2% of ChatGPT’s estimated user base. Enterprise contracts — which account for the majority of OpenAI’s revenue — were unaffected by consumer boycotts.
The real impact may be longer-term. Anthropic’s revenue is approaching $19 billion annually, growing roughly 10x year-over-year versus OpenAI’s 3.4x. The Pentagon deal gave privacy-conscious users and European enterprises a concrete reason to evaluate alternatives they might have otherwise ignored. Whether 2.5 million departures becomes a trend or a one-time protest depends on whether OpenAI’s subsequent decisions continue to provide migration triggers.
