If you are part of a group, don't assume that all the members are willing to use all the computer programmes or internet services that you use. When I participate in a group and, without any discussion, someone proposes we have a Skype or a Hangout, I realise that the person proposing it has not considered that there might be people who don't want to open a Skype or Gmail account. It is as though we wanted to force vegetarians to eat meat because it is more comfortable (or cheaper or whatever) to make a single plate according to the criteria of the acritical majority. That would be unacceptable, no? Well, in the same way, someone can refuse to use (or be used by) certain services. It is their right. The decision about which technologies to use is not only practical, it is also ethical.
