Not sure what "2TLDs" are, but regardless, that definition is incomplete in that it stops history at 2002 and is soon to be out of date in that the term sponsored and unsponsored is not being used for the TLDs to be approved under the current round. Community TLDs have some historical relationship to sponsored TLDs in that they are supported by some group. However, once delegated, that group is not necessarily in control of the TLD as is theoretically the case for Sponsored TLDs. However, the operator of the TLD does have a responsibility to maintain the community-based policies it specified in its application. Alan At 07/10/2012 11:43 PM, Salanieta T. Tamanikaiwaimaro wrote:

"gTLD
Most TLDs with three or more characters are referred to as "generic" TLDs, or "gTLDs". They can be subdivided into two types, "sponsored" TLDs (sTLDs) and "unsponsored TLDs (uTLDs), as described in more detail below.
In the 1980s, seven gTLDs (.com, .edu, .gov, .int, .mil, .net, and .org) were created. Domain names may be registered in three of these (.com, .net, and .org) without restriction; the other four have limited purposes. In 2001 & 2002 four new unsponsored TLDs (.biz, .info, .name, and .pro) were introduced. The other three new TLDs (.aero, .coop, and .museum) were sponsored.
Generally speaking, an unsponsored TLD operates under policies established by the global Internet community directly through the ICANN process, while a sponsored TLD is a specialized TLD that has a sponsor representing the narrower community that is most affected by the TLD. The sponsor thus carries out delegated policy-formulation responsibilities over many matters concerning the TLD."
I would assume that the policy formulation would include 2TLDs.
