[[Louis Rossmann - Video Directory|Louis Rossmann]], a consumer rights advocate and influencer, praised the project, but criticized the Lead Developer, Daniel Micay. A conversation between the two accused Rossmann of promoting harassment, slander, and attempted murder of Micay for commenting on the YouTube creator Techlore's video stating: "This is informative, and unfortunate." Micay subsequently threatened to ban Rossmann from their [[Matrix]] channel, and accused him of being discriminatory of people with autism.<ref>{{Cite web |last=Rossmann |first=Louis |date=26 May 2023 |title=Why I deleted GrapheneOS |url=https://www.youtube.com/watch?v=4To-F6W1NT0 |url-status=live |access-date=12 Aug 2025 |website=youtube.com}}</ref>
 
In 2026, GrapheneOS announced it was leaving the cloud provider [[OVHcloud]] by removing all active servers from France and citing concerns about France’s legal approach to encryption, surveillance, and data sovereignty rather than any technical issue with the company’s infrastructure. According to GrapheneOS, France’s support for proposed EU legislation commonly referred to as [[Chat Control]], which could require scanning user communications, raises the risk of encryption backdoors and government access to devices. OVHcloud CEO [[Octave Klaba]] responded that no incident had occurred involving GrapheneOS servers, suggesting the public explanation might imply a technical problem when none existed.
