Unless there will be another communication platform that could capture a good chunk of Facebook's users, Facebook is here to stay. A lot of Facebook features are just very difficult to implement in other platforms nowadays. One example is group messaging. WhatsApp has users from a wide range of age groups and no other platforms could easily compete with that. Communicating with our family, regardless of their age group, is a very crucial part of our culture and Facebook fills that gap. Another example is online selling. Buy-and-sell groups are thriving in Facebook because it's so easy to publish your products and immediately communicate with your potential customers. For example, in the Southeast Asian region, Facebook took a large chunk of users from Carousell, the most popular online selling platform there for years before Facebook released Marketplace. Even for me personally, I've tried to stop using Facebook for several months but in my home country, Facebook is just too integrated in its culture.
