Just wanted to let you know Tille Kottmann (https://twitter.com/deletescape) somewhat provides "Confidential and Proprietary" from a range of diverse Software which is/was publicly (but shouldn't) be available. From my understanding this leak is huge.
Overview: https://git.rip/explore/groups
Main Group:
https://git.rip/exconfidential
Telegram Channel: https://t.me/exconfidential
Companys can request to take stuff down but in the telegram group many stuff that was taken down on the git repo is still available while uploaded to mega.
To give you an Idea how much and what kind of leaks are mostly available I took some screenshots for a first impression. If you really searching/digging for something you really should check the Channel.
A Snapshot of the current Repo (some stuff already is taken down and folders are empty)
