I have worked for Status in the past, but that has not impacted the review of any apps. The spreadsheet has been reviewed thoroughly by others in the privacy space before I published it, and I encourage everyone to take a look and report any inaccuracies.
The criteria is objective on purpose. Everything on the spreadsheet can be verified for accuracy.
Status got a recommendation purely because it has proven itself to be resiliant to subpoenas and the cryptography is implemented well.
Nothing is sponsored, and no matter who I work for in the future, it won't impact the results. It's open source on GitHub, and I'm looking for contributors to decentralize control of the spreadsheets.
