I wouldn't use a META product if there were alternatives. But there are a lot of people who are very resistant to change. There are groups for their kids' school activities: soccer, tennis, music, and so on.
If you use Ubuntu Touch every day, a lightweight QML app like Greenline is perfect. You can check WhatsApp messages when needed. In an emergency, you can send a message like, “I'll be 10 minutes late.”
Personally, I prefer a WhatsApp alternative that is fast and stable, uses few resources, and adapts well to changes in WhatsApp’s data structure—such as the Go library, whatsmeow, protobuf structures, and WebSocket conditions on the servers.
I don’t need features like video or forms.
If someone wants all of WhatsApp’s features (including META AI) on Ubuntu Touch, then they have the wrong device.
Keep Greenline lean, efficient, and adaptable to changes at Meta for a long life on Ubuntu Touch. Many people and groups still need some time before they’re ready to switch to alternatives.
