The recent discussion centers around Facebook's alleged ban or restriction on posts related to Linux. Users report that their posts mentioning Linux or linking to well-known Linux distributions were quickly removed or flagged by Facebook's systems, claiming they could mislead users. Despite these claims, many people noted that Linux discussions still occur on the platform without issues, suggesting that the removals may be due to false positives from automated content scanning rather than an outright ban. This situation raises questions about Facebook's content moderation practices, particularly concerning technical communities and the underlying reasons for restricting certain discussions.
