While the problems aren’t universal they are happening and have been affecting travel for a not insignificant number of flights/people. People need to made aware that they should allow more time when arriving at an airport. They might not need it, everything might go smoothly but the reverse is also possible and when it does it can be hugely disruptive and potentially expensive.
If the media didn’t report it I am sure members of this forum would be rushing to criticise them. They’re damned if they do, damned if they don’t. Just because people don’t agree with an article doesn’t mean the reporting is scaremongering.
