i don't see how you could come to that conclusion. first please read my response here: https://news.ycombinator.com/item?id=41350245 and then reread my parent comment, in particular the last paragraph where i talk about "these companies" and "major messaging systems". it's clearly not referring to "all companies" and even less to a custom tool you built for your friends. at best "replace facebook with any other tool" could be interpreted as applying to your tool, but even then it should be pretty obvious that i could not possibly have a problem not being able to access your tool unless at least one of your friends is also my friend.
