On Tuesday, March 3, 2026, market intelligence reports from Sensor Tower and Appfigures confirmed a massive consumer backlash against OpenAI. Daily uninstalls of the ChatGPT mobile app skyrocketed by 295% on Saturday, February 28, immediately following the announcement of its partnership with the U.S. Department of Defense (rebranded as the Department of War).
The surge is a dramatic departure from the app’s typical 9% daily uninstall rate, signaling a significant shift in user sentiment regarding AI’s military applications.
The “Switch to Claude” Movement
While OpenAI saw an exodus, its rival Anthropic experienced a record-breaking surge in adoption. Users are moving to Claude as a direct protest against OpenAI’s new defense contract.
| Metric | ChatGPT (Feb 28 – Mar 2) | Claude (Feb 28 – Mar 2) |
| Uninstalls | +295% surge | Negligible |
| Downloads | -18% (Combined drop Sat/Sun) | +51% surge (on Saturday alone) |
| App Store Rank | Dropped out of Top 5 | Ranked #1 on U.S. App Store |
| 1-Star Ratings | +775% increase | Negligible |
- Platform Switching: Analysts noted that the simultaneous rise in Claude downloads and ChatGPT uninstalls suggests direct “platform switching.”
- Claude Outages: The influx of millions of new users caused Claude to go down twice in 24 hours (March 2), with over 4,000 reports on Downdetector as Anthropic struggled to scale its infrastructure to meet the “quit ChatGPT” demand.
Strategic Differences: OpenAI vs. Anthropic
The controversy highlights a fundamental split in how the two leading AI labs approach government cooperation:
- OpenAI’s “Patriotic” Deal: CEO Sam Altman defended the deal as a “patriotic duty,” though he later admitted the announcement was “rushed and sloppy.” OpenAI is now scrambling to amend the contract to explicitly prohibit domestic mass surveillance and lethal autonomous weapons.
- Anthropic’s “Red Lines”: Anthropic CEO Dario Amodei publicly rejected the Pentagon’s terms, leading to the company being labeled a “supply chain risk” and banned from federal use by President Trump. This “principled stand” is what triggered the massive surge in consumer support for Claude.
The “Memory Transfer” Tool
Anthropic capitalized on the momentum by launching a new feature on March 2 that allows users to import their memories from other chatbots in under 60 seconds.
- The Pitch: “Switch to Claude without starting over.”
- The Result: By lowering the “cost of switching,” Anthropic has successfully hollowed out OpenAI’s deepest moat—user context. Reportedly, over 700,000 users moved their digital “personalities” from ChatGPT to Claude in the first 48 hours of the tool’s release.
“You’ve spent months teaching another AI how you work. That context shouldn’t disappear… Claude can import what matters.” — Anthropic Landing Page
