I’m largely undecided on this. The button presence bugs me and doesn’t bug me. I was surprised to see Flickr in the product when I purchased v1. To me, Flickr is like PhotoBucket, so early 2000’s and passe. Right up there with Yahoo Photos. For me Flickr is a service that “never really caught on”. I guess however, it did for some. Google Groups is another one, but thank goodness they pulled it.
Personally, I don’t need a button for something I don’t own or isn’t integrated into my product. Do I want it to be removed over getting other enhancements or features (Sigi’s point), probably not, but I could live without it.
Admittedly, I was confused and conflicted after NIK v2 was announced. Need Lightroom, don’t need Lightroom. Integrated, not really integrated, but all will run as standalone apps. When it supports RAW, and I can launch it with a button press, or by selecting a “Export To Application” in RAW without conversion, I’ll buy it.
