It's possible to remove all the metadata in bridge using a script, this should work on most file types except some raw files.

Using ExtendScript Toolkit copy and paste the code into a new window, start Bridge - Edit - Preferences - Startup Scripts, click the "Reveal" button. This will open the folder that the script should be placed. Once that has been done close and restart Bridge and accept the new script.

To use select the documents in Bridge then "Mouse Control/Click menu" select "Remove XMP data"

#target bridge   
if( BridgeTalk.appName == "bridge" ) {  
removeXMPDAT = new MenuElement("command", "Remove XMP data", "at the end of Thumbnail");
}
removeXMPDAT.onSelect = function () { 
   removeXMPData();
   }
function removeXMPData(){
if( xmpLib == undefined ) {
  if( Folder.fs == "Windows" ){
   var pathToLib = Folder.startup.fsName + "/AdobeXMPScript.dll";
  } else {
   var pathToLib = Folder.startup.fsName + "/AdobeXMPScript.framework";
  }
  var libfile = new File( pathToLib );
  var xmpLib = new ExternalObject("lib:" + pathToLib );
 }
var sels = app.document.selections;
for (var a in sels){
var thumb = app.document.selections[a];
  var md = thumb.synchronousMetadata;  
  var xmp = new XMPMeta(md.serialize());
        try{
        XMPUtils.removeProperties(xmp, "", "", XMPConst.REMOVE_ALL_PROPERTIES);
        var updatedPacket = xmp.serialize(XMPConst.SERIALIZE_OMIT_PACKET_WRAPPER | XMPConst.SERIALIZE_USE_COMPACT_FORMAT);
        thumb.metadata = new Metadata(updatedPacket);
         }catch(e){alert(e);}
    }
}

I cannot possibly see why when people distribute files, for print for example,

they would want to distribute personal data, like camera serial number to

strangers.

To speak personally I really have no problem with that whatsoever, and also

as a professional photographer I have no problem that my clients can see the

other information also. There is nothing I wish to hide and there will be

very less clients that will look in to that information, they probably don't

even know it is there...

And stripping metadata from files while distributing means also stripping

copyright info and IPTC for description etc. That really sounds as horror to

me!!

But as said, that is personal, and the metadata with e.g. serial number

gives me the opportunity to filter all files taken with that camera in a

very easy way.

I often have stated: so many photographers so many workflows. But makes it

very hard for any vendor to fulfill all the wishes there are for

applications.

Maybe I am (and have been) being foolish.

Don't know, let's call it: just different...
