An anonymous reader shares a report: Ads in the stock keyboard app on a flagship smartphone added quietly via an app update, which then asks you to pay to remove them. You'd be hard pressed to come up with a more comically villainous thing for a phone manufacturer, or app developer, to pull on its users. Yet that's what's been happening to some HTC phone owners over the past day. HTC 10 owners seem to be worst affected (we're not seeing it on the newer U11 for what it's worth), with the ad bar taking up a good chunk of screen real estate. There's understandable outrage among HTC owners whose phones have started coughing up ads every time they open the keyboard. The consensus, obviously, is that this is not an OK place for ads to be appearing. In a statement, HTC said it was an error, and a fix is underway.
