Latest macOS Update Disables DisplayLink, Rendering Thousands of Monitors Dead (displaylink.com)
rh2600 writes: Four days ago, Apple's latest macOS 10.13.4 update broke DisplayLink protocol support (perhaps permanently), turning what may be hundreds of thousands of external monitors connected to MacBook Pros via DisplayLink into paperweights. Some days in, DisplayLink has yet to announce any solution, and most worryingly there are indications that this is a permanent change to macOS moving forward. Mac Rumors is reporting that "users of the popular Mac desktop extension app Duet Display are being advised not to update to macOS 10.13.4, due to 'critical bugs' that prevent the software from communicating with connected iOS devices used as extra displays." Users of other desktop extensions apps like Air Display and iDisplay are also reporting incompatibility with the latest version of macOS.

It's not a "bit" overblown; it's pure hyperbole/clickbait. The monitors are fine, and that includes with MacOS, the issue is that the monitors will no longer work when they are connected through a third party peripheral with drivers that do some encapsulation to send display data (amongst other things) over USB.
