Why can you send an email from Gmail to Yahoo, or an SMS from one network to another, but you can't send a message from Telegram to WhatsApp🤔?

A seemingly simple question, but it reveals a major problem in the world of modern technology 👇 ☝️ First: How do email and SMS work? Email and SMS are built on open protocols. Meaning: Any company or service can use the same technical rules. All services “understand” each other. Therefore, any email can be sent to any other email, regardless of the company. 👈 The key here: open standards. ✌️ Second: Why doesn't this happen between WhatsApp and Telegram? Because modern messaging applications operate on closed systems: Private protocol, private servers, private encryption ❌ Each application speaks a “different language,” and does not allow others to communicate with it directly. ✨ The important concept here: Interoperability Interoperability means: That different systems can communicate with each other, even if they are not from the same company. 👈 Like a phone: The type of device does not matter, the important thing is that you can call anyone. 👌 Why is this problem important? Because most people: ❌ Don't choose a messaging app because they like it ✅ Rather, it is forced, because everyone uses it Example: Your friends, family, work… they're all on WhatsApp Even if you prefer another app, you can't leave it 👈 This is called Lock-in (Digital Lock-in) The bigger the app gets, the more attached you become to it, even if it's not your real choice. ✌️✌️ What did the European Union do? The European Union intervened through a new law called: Digital Markets Act (DMA) His goal: 👈 Breaking the digital monopoly, giving the user freedom of choice, and imposing compatibility between major applications That is: you can choose the application you want, without being cut off from others. 🚀 Has the app actually started? Yes. WhatsApp has already started supporting communication with other messaging services in Europe The beginning is gradual and with basic features But it's a historic step toward a more open Internet 👏 Conclusion Email and SMS work because they are built on open protocols. Modern messaging applications are closed and create an indirect monopoly. 👈Interoperability is the solution -Europe began to impose this change -The user is the biggest beneficiary #idea_programmer #idea2dev
