I’m not defending Sony. Though I am also trying to discuss the industry standard practices that they operate in. That said how come Valve lets you keep any purchased game after the license is revoked but nearly every other digital store doesn’t or is hit and miss. It’s clearly something in the contract/licensing deal.
In other words Sony could choose to play hard ball and only sign contracts that permit continuous use of content after purchasing it. Thereby allowing something closer to actual ownership. Though the question is whether Sony and other digital marketplaces can convince rights holders to agree to such terms in the movie/tv industry.
Pretty sure Spotify is more powerless than you think. The record labels nearly burned their industry to the ground in the 2000s over digital piracy.
Netflix wouldn’t be around today if it wasn’t for their move into becoming their own movie studio thanks to just about every big Hollywood studio pulling out, arrogantly thinking that they can each run their own service for a bigger slice of the pie. Newsflash, it’s going really bad. Especially for Disney, who deserve everything coming to them.
I reckon if Spotify makes even a small move to undermine the big record labels, they would yank all the popular music. Spotify either wouldn’t last long or best case they down size into a niche music platform.
