First, it's "its" not "it's".
How ironic Disney is outsourcing its physical media to Sony, a company knowing for yoinking digital content from underneath subscribers making content no longer available. No, that will be kept by Disney, so whether through "The Disney Vault" or "Hey we're tired of paying residuals" they can just disappear content.
Sony, on the other hand, has to "support" physical media. I'm not sure what kind of "support" a BR or DVD needs other than a shelf, an occasional dusting, and careful hands to insert it into the soon-to-be-obsolete physical media player. There's a reason Plex, Emby, Kodi, Jellyfin, etc. are successful -- because if you or your buddy can afford some drives and a cheap server (e.g. NUC) you can digitize your own content, serve it up, and never deal with EITHER physical media (no thanks, Sony, you geohotz-raping liars) or digital media (no thanks, Disney, why don't you put yourself in The Disney Vault.)
It's not the 1960s anymore. Media servers not owned by the 17 "company name plus" are the rage. Those who don't adapt are left to rage at Disney and Sony.
