OnePlus seems to love, nay, thrive in controversy. From its "Never Settle" battle cry, to its exclusive invite system, to its premature retirement of last year's flagship, OnePlus seems to live out the phrase "bad publicity is still publicity". Just when you thought it was over, with a more or less "normal" launch of the OnePlus 5, here comes another one. Apparently, OnePlus has started sending OnePlus owners, most of them on the OnePlus 3 or 3T, ads and promos to upgrade to the latest model. And said owners aren't taking to kindly to the intrusion.
