I agree with you!
The Samsung Focus app apk is available to download at the SamMobile and APKMirror websites. Although the app's apk is available for download, Google will not grant Samsung Focus access to Gmail.
I downloaded the Samsung Focus apk from the APKMirror website and still use it on my devices. APKMirror is managed by Android Police.
Please be very careful if you download apps from sources outside of the Galaxy Store and Play Store.
