Every collection on FamilySearch has different copyright issues. There is no blanket rule.
In some cases, it affects whether the image is available for viewing. if so whether it is available for download; whether the above is from anywhere, or just from one of their centres; or just at Salt Lake City. Often the copyright still resides with whoever made available the original documents.
For example, South Africa, Free State Dutch Reformed Church Records, 1848-1956, has no word about copyright, but South Africa, Orange Free State, Estate Files, 1951-2006 has always had a copyright notice very much like the one you call "new".
I suspect that the practice of uploading actual images from Family Search is illegal, and personally I have stopped doing that. I can't see how it improves the profile. It's one click to see the FamilySearch image, and one click to see the one uploaded to WikiTree, but the FamilySearch viewer is better (and you can look at the previous or next frame for extra context).
I still use their transcriptions when I am in a hurry, usually when I don't consider the profile to be "mine", but those transcriptions are substantially inferior to e.g. the ones on eGGSA or to what experienced members of COGH or SA Roots should be able to do themselves.
