The problem I see there is it kills off certain marketing avenues ... and standard/established practices.
Further, I'm pretty sure I've seen/heard Googlers say it's fine to send stuff to someone who will review it ... and the chances are that the review will contain a link.
The problem here is that there is a distinct difference between doing something to obtain a link, and doing something that may contain a link.
All because G built an economy they failed to monitor/controll properly, and now have to go in hard/heavy to clean up the garbage they let build up.
So - Questions :
* Is Google going to slap the various sites that are linked to from "Which?", or other such sites/review systems?
* Will google view "Guest Posts" as going against their newer link guidelines?
* Is submitting content/products to a site/service that may result in a link to be considered as "spammy" - regardless of whether the potential for a link is in question/not the objective?
All I see is less clarity and more fear mongering, utilising the recent campaigns to brutalise site owners further.
