Duolingo, along with 24 other digital service providers including OpenAI and Cloudflare, has received a formal warning from Indonesia's Communication and Digital Affairs Ministry. The warning was issued for failing to register under the country's mandatory Electronic System Operator (PSE) regulations, a requirement for all digital platforms operating in the nation. The ministry has stated that this registration is a crucial measure to protect public interest and ensure Indonesia's digital sovereignty. The Indonesian government has indicated that it is now enforcing these rules more firmly after years of outreach. Authorities have warned that platforms that continue to ignore the registration requirement may face administrative sanctions, which could include the termination of access to their services within Indonesia. No market reaction to this specific news was available.
