Once popular in Eastern Europe, Viber is now a bloated, ad-driven app with weak privacy and little reason to use.

Why it’s a failure
- End-to-end encryption not enabled by default in all chats
- Owned by Rakuten, with poor transparency and data-sharing concerns
- Flooded with ads, stickers, and in-app purchases that degrade usability
- Consumes excessive resources and is often described as bloatware
- Lags far behind competitors in privacy, reliability, and features
- No compelling reason to use it when better options exist
