Definitely taken from the wild to be sold on the world market. The vast majority of Cyps coming out of China go back to one source, a "famous" exporter (a least in woodland perennial plant circles) who continues to successfully get plants out of the country. I guess it pays to have friends in high places.
A number of growers in Europe and the US have been working with micropropagating the Cyps making it out and at this point many have been successfully grown from seed. Having said that, US growers are not openly selling any of them. The reason is simple, they could get busted and their entire collections could be confiscated. It has happened to a few already. Enforcement of CITES is variable depending on the country. The US is very strict, but Canada much more lax. Same with the EU countries - plants are around for sale and 90% were wild taken. A number of species were grown in Germany before CITES took effect, so that is one way documentation has been created for some - they were in effect "grandfathered-in". Some of these have been exported to the US via different sources, most notably Paul Christian in the UK (one plant that comes to mind is C. froschii).
The flood of Chinese plants that hit the market in the late 90's were all wild collected. Like the bonanza on Paph. armeniacum and Paph. micranthum in the late 80's, the flow was unchecked for several years, but eventually the hammer came down. That is why you don't see them being sold openly anymore. The source didn't dry up, the regulations got tougher. BTW, most of those original plants that made it to the states entered into a veritable black hole - no body is talking about them so they are either dead or people are quietly growing them. Within the EU and Canada plants are more openly talked about and are being sold.
Take heart though Cyp growers! Due to the efforts of a number of people, more are coming available each year. One wholesaler in Belgium, Phytesia, in particular has been propagating and distributing a large number of species worldwide. As far as I know these are documented. Other companies have been busy as well, notably Judith Prins in Belgium, Paul Christian, Orchids by Post in the UK, and Werner Frosch in Germany (most of his stuff is hybrids, but not all). Others exist as well. Regarding Chinese companies, the only one that is micropropagating that I know of is Hengduan Mountains Biotechnology, LTD. in Sichuan. They aren't exporting yet, but keep your eyes open for plants in the coming years.
