Wouldn't be surprised if pretty much every communication service is doing this.

I sent a link to a large file over Viber and immediately some ip connected and started downloading. Stopped at 350mb of around 3.5gb. I get that they want to show thumbnails or whatnot, but they just don't discriminate between content types.

That is a great way to do a cross-link DDoS of unsolicited link opening services - send 1000 messages with google links on skype and send 1000 gmail messages with microsoft links there, all gigabytes in size...
