Hello,
I think there is an issue with the windshield becuase out of about 20 WRX owners I met in person in so cal meets. I think 5 or 6 of us had to deal with the cracked windshield. I think there is definitely a problem somewhere along the line and Subaru should do something about it. If anything go through insurance and just pay the deductable, depending on your insurance company if you think it's okay to report it as vandalism the deductable is probably much less. Ask your insurance company how they will cover it and go from there, and make sure they do a good job resealing hte rubber that connects to the bottom of the windshield. Roberto (Berto) replaced his windshield and they did a really poor job on sealing it and he can't do anything about it, which kinda sucks so I think it's best if you were there when they do the replacement and as soon as you see a problem have them fix it.
