You should look into https://small-tech.org/. I don't know if they're still active (I discovered them a few months ago, and they seemed active.) But they definitely have a similar point of view.
They are active. You can follow Aral Balkan [0] and Laura Kalbag [1] on the Fediverse. Aral is building a range of small-tech goodies, like Kitten [2], a small web development kit. And they are starting their 'Small is Beautiful' [3] livestreams again, using Owncast.
