" My point was that Tumblr's behavior was not outrageous, IMO."

So, I guess we'll agree to disagree. The fact that it may be more commonplace today does not make it less outrageous.

Outrageousness does not depend on how common something is, but society's view of it. To paraphrase an example from another ongoing thread as an example: If every airline starting throwing passengers out of the plane randomly, that doesn't make it less outrageous simply because it happens a lot.
