Copying from my comment below for context:
Job openings like these are messing things up for creatives who specialize in one area.
Now everyone looks for video editors who do audio. No more jobs for sound guys.
If you do graphic design, you are now expected to do animation and web design as well. Some even want you to do social media and video.
People who post things like these only want to save a buck. Heck that's why they outsource the jobs in say the Philippines and India. They don't want to pay their local rates.
And some Asian folks like this too because the going rate is higher than local rate here.
But it's literally ruining the livelihood of people in other fields.
As long as they pay for the skills they ask for and its a doable workload, I don't see the issue. Its not as if they are asking for master degrees or to do it all in an unpaid internship.
