What's your definition of 'closed'?
- a3_nm 10y agoI cannot interact with WhatsApp users without registering an account with WhatsApp and running proprietary code published by WhatsApp. Compare with email, where I can email friends at whatever provider without registering with them or having to run their code.
- Freak_NL 10y agoAdditionally, you can't even use WhatsApp without a mobile phone number, and effectively you need a smartphone with a supported mobile operating system of their choosing. That's pretty closed.
