People choosing to use a walled garden are being punished by those who would rather not? You may have that reversed - this isn't about thinking you're "above" a communication method, but it is worth noting that Facebook requires using their specific service while many other methods (phone, email, etc.) can be used from a variety of providers. So, saying "I only use Facebook to communicate" and expecting others to conform is a bit more naturally presumptuous than choosing to leave Facebook - and it's a fair point that if a relationship can't survive not using a specific proprietary tool, then maybe it wasn't that strong of a relationship.
