What a rubbish article. Lacking on details and misleading as week as having another jibe at google+.
For one thing, the post by huawei was posted to Google+, Facebook and Twitter but Google+ is the only social media network that doesn't compress photos and retains the ability of its users to view the exif info.
Secondly, the text in the post doesn't specifically say that the photo was taken using a P9, but it is implied. Why did you not include what Huawei actually said in the post?
Thirdly, it wasn't Android police that uncovered it, but a couple of saavy Google+ users (we are legion) including myself that tagged a few people in the media to alert them of the deception. If you had have included a screenshot, it would have shown that.
Fourthly, if you really were wanting to grow your audience, targeted posting to Google+ would be the way to do it.
Fifthly, as Mike Elgan points out, the same post on Facebook and Twitter was met with a positive response, and concludes that Google+ are the most intelligent, saavy people in the world. Google+ is somewhere that intelligent people can have intellectual conversations without resorting to the hate and mud slinging of twitter, and there is the ability to speak to each other in long form.
Seventhly, thanks for reading to the end, this article appeared in my Google Now feed, you'll see me over on Google+.
