In many ways, hasn't this always been a problem of professional magazine writers?
Back in the day, a decent article would take months to write - now "journalists" propagate stories of celebrities, because only clicks matter, not impact.
It isn't about the borrowing of content or ideas, it is the passing of as expert/ skill when there is no experience at all. Watching a medical drama doesn't make a person a surgeon.
I used to watermark, but haven't for ages!! How I see it is, I have the originals and all the exif data to back it up.
Anything that makes the influencer go away, I'm good with!
What happened to the influencers who had pull because they offered the world something valuable?
When I think "influencers" I can only think the worst examples, such as from Instagram and Youtube. But you're right, there are probably good influencers too. I would tend to think the good ones will have the ability to roll with whatever it changes to in the future, whereas the bad ones will not have that ability and will disappear.
