edit: as far as examples in detail, I have none, but I would honestly be extremely surprised if there were fewer than a dozen in the world's current state, probably hundreds through time. If I come up with one, I'll be sure to include it.
In the meantime: do you wish to argue that all such acts (name of culture => modified name as product => simplification dropping the modification) are offensive, or is this one somehow worse? I ask not to ridicule, but that this stance seems (to me) to be relatively new or rare, and favoring this instance as something far more offensive than I would find it if applied to me (Best Buy's Geek Squad being a mostly similar example, OTOH. I find them mildly annoying, but nothing more).
Basically, you (the collective-you, that is) have a point, but I and probably many others here think you're overreacting, though we might be swayed by a convincing argument.
