No, it isn't short-sighted. On the contrary it is a matter of letting Microsoft earn their trust again at a reasonable pace after almost two decades of systematic abuse. The Halloween documents where published 1998 and it is only the last year or so since they've begun dipping their toes in open source waters. They've thoroughly earned their shame.
Besides, even if everyone at Microsoft has changed attitude that's no excuse. Microsoft has had five years since the acquisition of Skype in 2011. Isn't it, by now, time to stop blaming their predecessors and own up to the current state of affairs?
