our home was built in the mid 90's and we are now experiencing a significant rot issue under our cedar siding. Our neighborhood was built around the same time and there at least 8-10 homes with the same issue. We are going to join up and solve our issues but need more feedback from others that have the same problem with a Typar Wrap from the same period.
Well I hate to say but in the mid 90's typar was there as an air barrier, not to shed moisture away from your sheathing. That job falls to the siding. The last 10 years or so they have been marketing the ability to shed water but more as a backup to the siding.
If you want to blame someone, first I would find out how the moisture got back there, then find out who or what to go after. If it is the same in 8-10 houses, the first question would be if they were all built by the same builder, if so then that's where you start.

I am having the same issue with rot on my house. It was only found when work was started for an addition. Clapboards are perfect, perhaps a little water staining on the back. Plywood underneath is rotted. This is not just around doors and windows which were all installed and flashed appropriately. The house is 12 years old. The whole neighborhood was built using Typar and cedar clapboard and many homes now have extensive rot. The homes were built by 4 different builders and built to code. The person who is doing my addition has now learned that so many houses have this problem that there are new recommendations on how to use Typar. I heard that there is a lawsuit in RI against the manufacturer. Any suggestions/information?
