When I read this this morning, I had concerns, but then I did some research. The SDKs source is fully available for all to look at and compile. The main issue that people bring up is the license that states:
3.3 You may not use this SDK to develop applications for use with software other
than Bitwarden (including non-compatible implementations of Bitwarden) or to
develop another SDK.
This part seems to be what most people take issue with, as it makes the sdk no longer modifiable, yet a requirement of the core source itself. The head of BitWarden has come out and stated the SDK being required to compile BitWarden was a mistake, however, and if this proves to be true (which I have no reason to doubt) then I see no reason why any of this is an issue.
From a security standpoint, since the SDK is source available, it can be audited by anyone still (and compiled) so personally, I’m fine with this.
Look into the sins of your past!
Love as if today were your last!
