I think this is a combination of kind-hearted, but contextually unaware, people shocked that wind turbines can kill birds, and bad-faith attempts to stigmatise wind turbines for disingeneous (or at least biased) reasons. Others have pointed out that there probably is a difference in the kinds of birds killed by cats vs wind turbines, but I've not seen any report breaking down the deaths by species (not that I've looked).
