Why you are not charging a single penny?

What type of ecosystem i this?

Yes you are right at this point!

WhatsApp’s ability to support 50 billion messages a day with such a small team is really impressive! It’s all about efficient engineering, smart data optimization, and using scalable cloud services. Their focus on simple, high-performance design and leveraging automation has been key to managing such massive traffic. By the way, if you’re into optimizing apps for better performance, I recently found that Lulubox Pro 6.17.0 APK download offers great ways to tweak and manage apps more smoothly, which can be useful for improving your mobile app experience overall. Just make sure to download it from trusted sources!
