Many institutions are committed to #sustainability. For this reason alone, #digitalsovereignty should be important to them. Two years ago, scientists from @JLBe@mastodon.social and its network published a study on the sustainable use of #smartphones. 👉 https://onlinelibrary.wiley.com/doi/full/10.1002/sd.2995 It showed that typical #socialmedia apps such as #Instagram, #TikTok, #YouTube, etc. on #cellphones conflict with a number of sustainability goals. Among other things, they cause high #energy consumption, which is not incurred directly on the smartphone, but in #datacenters and transmission networks. A large proportion of the #electricity consumption is due to the fact that these apps do not respect #privacy and data protection, but instead spy on users. The use of #Mastodon and other #Fediverse services is more sustainable because much less data is exchanged between users' smartphones and the service instances.
