This is a false equivalence. Cyclechat is a forum - something now considered "social media" which exists to allow people with similar interests to share ideas and conversations. It has no other purpose. Facebook on the contrary, is a marketing company which has a business model to gather as much data as possible and in particular get information about peoples' social network. The social media part is merely the mechanism that is used to feed its requirement for data. It is a means to an end, rather than the end in itself as CC is.
