Google CEO Sundar Pichai Warns Android Users Not to Sideload Apps
(www.gizmochina.com)
This is a most excellent place for technology news and articles.
There may be a little bit of vendor lock in here, but it definitely is also about security. A lot of people are completely oblivious when it comes to tech. Sideloading is easy and there are tons of guides for it, so if someone is tech illiterate they can just follow the guide and install malware ridden apps easily.
At least they can remotely uninstall malware ridden apps installed from the Play Store, you may not like that feature, but at least it's better than sideloading a malware ridden app and not knowing about it.
Sounds like a good opportunity for a learning experience then.
