Too Long; Didn't Read
Google and Apple are cutting outdated apps across their app stores. Google is already looking at hiding apps that haven’t been updated in 2 years from November this year. This poses a massive problem for persistency and preservation of digital artefacts that no-one wants or avatars and items that are abandoned in worlds but have to remain for the promise of persistency. Google Play is cutting 869,000 apps and Apple removing 650,000. Data storage doesn't come for free and archiving procedures are going to have to become a process that is considered far more in advance than some decentralised world builders are willing to admit.
