Because money. And hassle. For example, I host my personal sites and a bunch of my friends and friends' businesses' sites for free. Sites that otherwise wouldn't be online. I do it via the Rackspace Cloud Sites platform because it has better performance than typical 'shared' hosting. If I want an SSL certificate running on one of them, it's $20 per month per domain... in addition to the actual yearly cost for the certificate. I don't have that for sites I give away for free. That's in addition to the hassle for the 3 days and multiple faxes and phone calls it takes for me to renew my businesses that do use SSL certs from reputable providers (as opposed to the $10-$20 a year providers that don't bother to even check who is buying the cert). The SSL cert setup isn't terribly secure, is a big hassle, and costs a prohibitive amount of money for most smaller sites.
