This is a tech community, and I like tech metaphors - it’s like old CCTVs were inside the firewall and these new services our outside the firewall. In the old model, sharing your data (videos) was opt in each time. You could be sure that only you had access to the data unless you chose to share it. In the new model, you are always sharing, and these hacks show you don’t really even know who you are sharing with.
