Why would it?
Do you regularly visit "hot-iphone-porn-apps.info" and other untrusted sites? Do you expect sites you do visit, like "google.com" or such, are going to serve up malware?
Do you expect hackers who build these very labor-intensive exploit chains will want to try and hit as many low-value targets as possible, leading to apple patching the exploit quickly, or to try and hit high-value targets only so it's not noticed by apple as quickly and can be used against more high-value targets to make more money in total than doing a "spray and pray" with it?
What thought process do you think would lead to using the exploit against as many people as possible vs selling it to zerodium.com or a similar company for more money than you can get from spraying, and then zerodium reselling it to israel to hack into the iphones of a few key palestinians?
