Nothing new. I worked in a newsroom as an intern and most major news stations rely (maybe, relied, it's been a few years) on a tool like ENPS. It's made by the Associated Press and has a "wire" feature where new stories come into. So, e.g., if there was a plane crash, that message would be pushed out to all newsrooms that rely on ENPS. The news producers were lazy, too. They'd literally take the script that ENPS push…
Where do you suggest people go to get their news instead ?
It also depends on what the story involves. The example I gave above—a plane crash—is very objective. Something bad happened, people were likely hurt, authorities are investigating, etc. Where it starts to get murky is when a story taps into an ongoing narrative like gun control.
Notice how the major news networks were (and still are) each pushing their own narrative around the Parkland shooting. The left-leaning media were pushing the need for more gun control and anchoring that to the victims, the right was babbling on about how the left was just trying to steal everyone's guns and why gun ownership is positive. It's where you're being told that one side is "evil" that your antennae should go up.
In situations like these, it's worth considering what is factually true, what is opinion/emotionally-driven bias, and working hard to form your own opinions.
