When I explain to others what I do for a living, I often ask why it is that we are not surprised that one can use a Gmail account to send an email to someone who uses an Outlook account, yet many people fully accept that you can’t send a message to someone using WhatsApp from a Telegram account. We’re not surprised that we can use our phone to set up a call with someone who uses a different brand of phone (or is subscribed to a different provider), yet, for instant messaging, we find ourselves in a world of walled gardens.Walled gardens refer to ecosystems where companies control access to their platforms and restrict users’ ability to freely interact with other services, creating barriers that prevent open communication and fair competition.
