Personally, if photography is a vital source of income, and your employer/clients wants you to stop using HDR, then you have to do as you are told.
Now, if photography is a mere hobby, you can do pretty much anything in pursuit of your own personal joy. If that means collecting cameras, lenses, then by all means, indulge. If that means doing HDR, and running them to a gamut of software, to every single photo you've taken, go ahead, if that's what you want. If that means scouring every technical review in the net, fine! Bottomline is, if photography is a mere hobby, let's not get swayed by every little dos and donts we read. It's our own joy, our own happiness, we know our own selves more than these bloggers.
