No, it does not. SIMPLE is a set of specifications for chat and presence.
https://datatracker.ietf.org/wg/simple/documents/
For SIMPLE chat, MSRP protocol has been defined.
https://tools.ietf.org/html/rfc4975 <https://tools.ietf.org/html/rfc4975>

Presence is not chat, is something else than chat. Nevertheless Blink implements both chat and presence from SIMPLE specifications and CSipSimple implements neither of them.

No, they cannot as CSipSimple has not implemented anything from SIP SIMPLE specifications.
I am not sure they claimed otherwise either, where have you see that CSipSimple implements SIMPLE specs?
