so much yes! People in USA and Europa do not understand this. Not everybody in the world has many X Mbit/s on mobile (many have less than 1Mbit/s) and Gigabyte download limits. Companies like Facebook, Instagram and even WhatsApp understand this problems. Some companies like Snapchat do not even know what I'm talking about. The downsite of websites going SSL is that normal Google Chrome compression does not work. While Opera Mini is maybe not as secure (because it does server side rendering even on SSL) it helps a lot on that problem in countries with low bandwidth.
