I'm surprised at the reaction. If you have even a hint of a dream of making money off of your work, you'd be silly not to take any opportunity you can to let people know whose image it is that they're seeing. I'm sort of a "tweener" - I came out of school in '94 and went into the traditional agency world, but quickly found myself moving into what was then the first stages of commercial online brand building and advertising. Good for me - I got in early, did ok and managed to muddle my way to a decent career.
On the other hand, I established myself *before* the 20xx era of social media, and my skillset has slowly become outdated as I have stayed in a managerial position (as opposed to being on the "front lines" of marketing), and I've had to go back and update my skillset appropriately as my photographic work has started to get a bit of traction, and as I've been doing more hands-on advertising work because, basically, I have to.
In all honesty I find it uncomfortable - uncomfortable talking about how "awesome" I am (please take that as the reality of what you have to say - not what I think), and uncomfortable screaming at people to "look at meee!" But in the influencer/social-media-driven marketing landscape today, unless you're drawing eyeballs simply by virtue of being a celebrity, sadly, that's the way it is.
Warhol turned out to be right - a good image *is* just one of a celebrity that's in focus, and that's sort of disgusting, but nothing worth getting upset over IMHO - it's just today's business reality.
