FWIU, CD-Rs can be problematic as they age as they can have advanced deterioration. Also, if one holds onto CDs in hopes of future re-sell (at loss or gain), then you have that option. CD-Rs basically have no resale value.
I think the main issue with CD-R production is the lack of transparency about their use on the part of sellers. Those who sell them and openly state they're CD-Rs - fine, and the buyer can make an educated purchase. No disclosure results in unhappy customers who were expecting a different type of product.
