- on one side there is the increasing number of features in WhatsApp that nobody asked for and that make the experience worse and worse, I agree. Yet, on the other side of the world a 1B people in China use WeChat for so many things beside communicating, so I understand Meta's appetite to become the West WeChat. Still I hate it. - on the other side there is the business model of WhatsApp. Or the complete lack of it. It's 100% unrealistic that a global, always on, high availability, high security service is free. These things are expensive and they need to be monetized.
It's either ads, either fees on extra services they are providing through the app, either a monthly subscription. Now, I think nobody would pay for WhatsApp and they would lose their market immediately if they went that route (for many good reasons). They tried hard to position WhatsApp as WeChat, failing at that (for many good reasons). Ads is the only thing that is left IMO.
