> And sure, stackoverflow copying is a thing, but they clearly tell you the license by which you can use said code: https://creativecommons.org/licenses/by-sa/4.0/

There are posts under an earlier license which was CC BY-SA 3.0.

There are people who don't have accounts anymore or haven't logged in to accept an updated license.

Only the changes to the post after the 3.0 to 4.0 in the above case are technically licensed under 4.0 (the original post is still under 3.0).

Furthermore, Stack Overflow didn't follow the proper process for updating the license.

For example - https://stackoverflow.com/posts/11574647/timeline

Look at the license and the Aug 22 change and consider if that removing "Hope that helps" was a sufficient change to relicense it.
