Arguments for curl are incorrect.

I needed to edit this script as follows before it would download correctly:

diff --git a/fetch-latest-widevine.sh b/fetch-latest-widevine.sh
index 5d31ffe..99c2c25 100755
--- a/fetch-latest-widevine.sh

 # Detect wget/curl
 DLTOOL=""
-which wget && DLTOOL="wget -O -"
-which curl && DLTOOL="curl -L"
+if which wget; then
+    DLTOOL="wget -O -"
+elif which curl; then
+    DLTOOL="curl --remote-name -L"
+fi
 [[ -z ${DLTOOL} ]] && echo "No download tool found on this system" 1>&2 && exit 1
 
 # Begin download

I must assume that most people are using wget, and do not have curl installed on their systems.
