I feel that retaining the manufacturer's descriptions is useful for users, though it shouldn't be the only content on the page.If google is expecting people to add their own 100% content for products, without retaining any manufacturer's description, it isn't good for users.
I'm 100% behind you on this. Removing aggregated product descriptions is neither practical from the users point of view and the site owners, where the expense could not be met for large sites. And writing replacement unique content could be a waste.
Siteowners would have to be on the look out for other improvements which can be more economically applied that can reverse them out of this mess.
