But we can use it like [[File:Example.jpeg|link=]] or [[File:Example.jpeg|link=Some page]] which would suppress or substitute the link with another link. We can also use images via css or scripts for some backgrounds and so on which is not about the link-parameter but has the same issue in core.
The question is how attribution requirement is being fulfilled in the latter case?
What is general community consensus and WMF position upon it?

From what I've seen on enwiki, this mainly applies to images used as
navigation icons or decoration in templates.
Whenever I see an image requiring attribution or notice of license (which basically means "anything that's not public domain or CC0") that is using the "link=" parameter, I'll fix it with an appropriate edit summary. Sometimes it's possible to find or create a replacement image that's public domain or CC0 which can be used instead of the problematic image, or sometimes I just remove the "link=". In some cases the link necessary for attribution is supplied in some other way, e.g. by superimposing an "info" icon on the image with the necessary link.
A few years back I tried to make a user script that would highlight problematic images, but the plethora of licensing categories (particularly on Commons) made it too difficult to keep up with. Maybe the new Structured Data planning can make this possible.
