The Day When Open Science Blocked Science - A Case Study in Scientific Gatekeeping

Open science is commonly presented as a historical expansion of scientific freedom, accessibility, transparency, and dissemination. Repositories, indexing infrastructures, persistent identifiers, and distributed metadata systems are often described as mechanisms designed to reduce barriers between scientific production and public access. This article examines a documented case that reveals a tension within this narrative. A series of theoretical physics manuscripts criticizing established frameworks in high-energy physics were assigned DOIs, indexed, archived, and publicly disseminated through modern scholarly infrastructures. Subsequently, the records were removed from Zenodo and the author account was blocked under the public justification that the content was ``out of scope''. No scientific refutation, mathematical analysis, referee report, or technical assessment accompanied the action. The significance of the case does not depend on the correctness of the manuscripts themselves. The central question is institutional rather than theoretical. What happens when infrastructures that publicly define themselves as open repositories begin to perform functions traditionally associated with editorial gatekeeping? At what point does administrative moderation become indistinguishable from scientific filtering? Can an infrastructure simultaneously claim neutrality while exercising discretionary control over scientific visibility? The analysis becomes particularly revealing when contrasted with the persistence of the same body of work across independent scholarly systems. While records were removed locally, the broader scientific trace remained visible through DOI registration agencies, ORCID synchronization, DataCite Commons, author profiles, and external indexing services. The attempted removal therefore failed to erase the scientific record and instead generated a second record: documentation of the removal itself. The article argues that modern scientific infrastructures face a fundamental paradox. The more distributed the scholarly ecosystem becomes, the less effective administrative erasure becomes. At the same time, the distinction between repository, publisher, archive, and gatekeeper becomes increasingly blurred. The case examined here illustrates how contemporary debates about open science are no longer primarily questions of access, but questions of legitimacy, visibility, and institutional authority. Three centuries after Galileo, the central problem may no longer be whether scientific ideas can be published, but who possesses the authority to decide which ideas remain visible within the infrastructures that claim to be open.
