The Fediverse - especially the microblogging side of it - has deep issues when it comes to environmental sustainability.
And the high resource requirements, which result from an incredible level of redundancy, aren’t just bad environmentally: they make running a server more costly, and increase our reliance on Big Tech’s infrastructure.
I wrote about all this, along with some suggestions for how we can improve things somewhat.
I hear you on this - Akkoma does this by default, but the issue there is, let’s say someone on a tiny server posts an image, even a relatively small one - if it gets boosted by an account with 10k followers, that small server will effectively get DDOSed, assuming enough of those clients are online.
