I feel ya, deleting whatsapp will not be great for my social life. Neither was deleting facebook, at least at the time when it was still being used. Whatsapp has inserted itself into the social fabric as a benevolent offering and now that we are all locked in we get what we payed for.
But that is all the more reason to get rid of it. Of course this makes life complicated. But if we don't make these hard choices and 'sacrifices', it will never stop. They will keep eroding away at our privacy and freedom. It will only become harder the longer we wait.
This kind of things will keep happening though as long as we allow monopolies and closed platforms. We should really be more careful with accepting these companies into our lives.
