See buddy.. Television and Streaming are two different businesses.. It's not just with Malayalam but with Telugu, Kannada and Tamil as well... It's not always necessary that Hotstar to acquire rights because Star is acquiring them for broadcasting.. It's as simple as that. Also, Hotstar offers Indian content freely unlike other platforms which is also a thing they will concentrate on to get ROI.. Even if u take Hindi market as well Hotstar doesn't necessarily own most of the movies Star own for broadcasting... Regarding Multiplex movies, they are slowing entering each market.. Now their priority is to get Telugu films and Shows out once it's out of the way they will go to the other markets as well. BTW, if u don't already know they do acquire big malayali films more so than they do with Telugu films for example the upcoming juggernaut Marakkar is acquired by them only... The streaming business more crowded than the television business now, so they don't necessarily have the budgets to acquire everything...
