Changing from VHS to other media (e.g. DVD) had very significant and apparent advantage even to the average user. Also, it's not a communication tool so as long as we could buy the player for the new format and we could get the media ourselves, it was all good.
We all know that Facebook is shxt but if everyone else doesn't feel the need to change, I still need to keep the account, especially, WhatsApp has very high acceptance in business usage too due to historical reasons and it being cross platform and tied to phone number. Telegram, although many of us know about it, is simply unknown to most people. So it's not whether I want to change it or not, it's whether other people are aware there are other choices and that they feel the urge to change. People hate changes.
Of course, it takes courage to change. I closed my Facebook account more than a year ago. The account was with many years of photos and communications, but I still managed to do it, mainly because not many people care about Facebook anymore, and no one uses Facebook messenger here except very few business use. I opened a dummy account just in case for some business pages and business chat accounts. But of course, Facebook still can track me via the dummy account. I just try to avoid using it as much as I can. But then they have Instagram, another extremely popular social network. This one I still can't escape yet.
There is still a long way to go for people to wake up about WhatsApp. Well, actually I don't think many people care, even if they are clearly aware that Facebook is manipulating their sensitive personal data. Most people don't even know how extensive the tracking is, or they just don't care. Don't put too much hope in humanity - especially when we witnessed the chaos happening in many places in the world now.
