Spent almost 12 years at Amazon till early 2023 and some of this is very surprising to me. I know the annoying slack retention policy but I had never heard of tickets, issues, or wikis or even git commits being auto deleted. When I was there I could go back a decade and open up old tickets or wikis. Has things changed so much in less than two years?
