This is CYA boilerplate for all services and sounds worse than it is.
1.
Reproduce = spread your data on multiple regions/drives/computers/etc inside their data storage systems
Modify = format changes
Create derivative works = automatic translation, format changes etc
publish = show your files to people
publicly perform = show your files to people (for video)
publicly display = show your files to people (images)
distribute = show your files to people
2. Because their datacenter cannot delete files instantly, another CYA point that prevents people from unsubscribing and suing if their files don't disappear the same instant they click the button.
All of that is just shitty legalese that attempts to prevent frivolous lawsuits, and every time some engineer takes it literally and assumes the worst.
