You don't need to worry about ransomware destroying the data on your writable DVDs, the discs themselves can do that fine.

The problem goes away if you burn slow, no faster than half the disc's max speed, to adequately affect the dye. I have CD-Rs and DVD-Rs that are 20 years old and work great. Inherent rot is mainly a problem with pressed discs which use aluminum instead of silver or gold for the reflective layer.
I burn my CD-Rs at a very low speed, like someone else mentioned below, so the laser does a better burn. I don't use CD-Rs as primary backup. I have 10 external hard drives, 20 thumb drives, and do a CD-R only once every couple of weeks. I just feel better having multiple different hardware devices used.
Yeah disc rot is a real problem. CD/DVD-R are great when it comes to physically store drives (they don't take much space on a shelf and are easely sent via mail) but I'd rather use a hard drive and the cloud for my backups now.
