we knew some of these factors for more than 3 years, and little will change going forward
large screen - if you are tempted to consume more video, this is a good thing right?
background apps downloading data - this is what you get for multi-tasking. easily handled, and not exactly a problem.
data saving updates not reaching the handsets - ermm... so what if a phone is still on gingerbread, this is again not a biggie. maybe a little, but not so much is going to change or can be done about this. don't think the fine tuning on this dept is going to bring down the data use considerably.
not going into other points because they were not raised by the paper. but imagine the opposite headline is equally infuriating. Android users not using as much data as iOS. (original story made comparison)
so what is the problem? TOI should be re-named passtimes of india. when media is "sold out" it means figuring out new ways to charge for ads. so the ad may come in the middle of the story, but the content itself is not sold. it's badly written, factually inaccurate, mostly copied from the internet, not spell checked, but it's not "sold".
