Searching with Bing may be "more satisfactory" -- if the proprietary property rights of photographers, artists, and illustrators are not a great concern.
I echo what others have said. Hundreds of professional clip art images that I relied heavily on are now no longer available. I find it quite frustrating that MS's answer is "just go do a search for Clip Art on Bing". I'm not so much bothered by MS driving
customers to an ad-supported MS site. If that's what they need to do to stay profitable in the competitive productivity software space, so be it. What I find troubling is the impression it leaves that somehow the clip art that MS provides is equivalent to
going and doing a search on the web.
As an Ethics instructor at a local college, I have always taken great care to make sure I use images in my class presentations that are not restricted copyrighted material. I even went to the trouble of checking in the MS license to make sure that clip art
could be used in an educational setting.
I always felt the MS clip art galleries was one of the ways MS added value to its tools. It set them apart from much cheaper (read free!) productivity tools out there. The clip art galleries were a great way to maximize the effectiveness of PowerPoint. In
fact, I first discovered them many years ago through Cliff Atkinson's "Beyond Bullet Points" -- a great Microsoft Press book on how to maximize your use of PowerPoint!
Sadly, I do not have time to search on Bing and confirm the licensing agreement of every single image I may or may not want to use. I'm now stuck either providing a far less media-rich educational experience for my students or paying out of pocket for an image
service.
I'm not sure why I'm paying for the MS Office suite any more.
