In reply to Wassim.

I personally don't think that this is a problem at all since cheap, domain-validated certificates have been around for ages and any site can purchase and install those.

Encrypted connection protects visitors from a variety of attacks and possible exploits. Now, whether they will willingly to to a dangerous site is up to the given individual to decide. I don't really think that someone will decide to share information or even make a purchase solely because of a green padlock in their browsers. On the contrary, a red "INSECURE" label is scary enough at least to make them check twice whether that's a legitimate website :)
