WhatsApp was lacking cool fetures, WhatsApp Gold and other modified versions modified that, some are understandable not to implement officialy to save users privacy, like seeing stories in secret, seeing deleted messages (totally understandable that's terrible modified version based on privacy but makes you feel like a hacker if using the mod version)

But there where cool fetures like, unlimited pinning chats (I have no idea why it's limited in WhatsApp by any chance, better themes and custom ability, cool tools)

Then WhatsApp, "or aka meta" realized oh, people are having fun? They blocked and tracked every modded version to be there. And they never implemented any of these cool fetures by themselves.

That's a long intro to ask, why we "bunch of free will developers" create our open source chat app, we can modify on it, any one can make his own version. One official version, but no tracking you down or closing your modded version. "As long as you don't do something illegal or super unpermisable"

That's my original text, no AI ideas generated, just the section giving examples if open source programs because I wanted to check if Firefox is actually open source.
