Full diff between the current and upcoming versions of Instagram ToS here.
The change should also appear as a commit here at the ToSBack project, once it’s live (in a month). It’s a pretty cool project, they track ToS and other policy docs of many sites in the crawl
and crawl_reviewed
folders, and commit each version to the repo so we can track their histories. It looks like Instagram updates their ToS from time to time without notice - even while adding the note to tell you that things are changing in December, they snuck in a few other changes, for eg. saying that they could keep your content for 90 days or possibly forever after you delete your account.
Another project similar to ToSBack: https://github.com/ambanum/CGUs-versions
Somewhat easier to use, cleaner commits.
