I think is a win-win option 

 Depends on many factors 

 For example? 

 See my reply in the thread 

 Thanks! 

 yes it would make more business sense the other way around, default is expiring, pay for the option of permanent storage 

 On a surface, yes, if you think deeper, then not really but increases costs. 

 in what way? most people don’t even know the media host they use

it also comes with other problems like moderation also

they also need to provide some value proposition to paid users which could be also expiring media
