Why would Abbott risk exposing the details about Treadstone to an outsider?
I find the imdb answer isn't quite plausible. When Landy first confronts Abbott about Treadstone, he gets into panic and couldn't believe Landy has traced the fingerprint to Treadstone.
Why would Abbott risk exposing the details about Treadstone to an outsider? He doesn't need to frame Bourne because she doesn't know anything about Neski's murder.
Best Answer
If the 'frame' had gone to plan, Bourne would have been dead and Abbott would not have been worried about Landy tracing the fingerprints back to Bourne and Treadstone.
'Dead in a ditch. Drunk in a Bar in Mogadishu' - at the point that Landy first confronts Abbott he is still under the impression that Kirril had assassinated Bourne and was confident that any investigation would reach a dead end (pun intended).
It is only once Bourne resurfaces in Italy and Abbott realises that he is still alive that things begin to go sideways for him, hence his desperate attempts to push the agenda to have Bourne killed before he can be contacted by Landy and her team.
