The very important point of today's world - data protection - is not covered at all. For customers, it's better to give their data consciously to one provider within one chosen jurisdiction than moving personal data, documents, activity logs, etc within multiple 3rd parties, as well as to do due diligence on any web service they provide any data. Please, respect your customers and don't share their activity when it's not necessary and cost just a few hundreds bucks per month. Treating humans as "units" instead as people with rights is a big problem of IT businesses.
