Yes, that article does use religion as a reason, but he is selling Islamic friendly sex aids/toys to Muslims online. The person selling the items being Turkish has very little to do with it. Someone in Britain, Germany, France, America or anywhere else could set up an online Islam friendly sex toy website, but that wouldn't mean that everyone else in the country are Muslim, it would mean they're selling toys to cater for a certain religion.
The article even says that there is sex toy shops in Turkey, albeit not very pleasant sounding ones, but there is also Turkish sex toy websites in Turkey. That article is stating that the seller has made a Islam friendly website.
Islam and Turkey are two different things.
