I have a few kindles, have upgraded over the years and have been able to use them all in the same manner:

With a new device I connect it to the internet and update the firmware to the latest version (the factory installed version has had a lot of missing functionality in my experience). Then I block it from my network, delete the AP entry and put it permanently into airplane mode.

When purchasing an ebook from Amazon you can download it for usb transfer and I organize it on my laptop with Calibre.

Calibre can also strip drm, but if you’re transferring it to the device you downloaded it for it isn’t necessary.

Amazon may at some point in the future change all of this, but the content I have already downloaded can not be revoked and is usable outside the Amazon ecosystem if the drm is removed.

The form of this kind of social media has got the same set of upsides and downsides as it does on Reddit. It won’t be exactly the same because the people are different, but the problems aren’t that different and the people aren’t that different either.

As a mostly lurker I find the experience pretty similar. I scroll through and find some interesting articles, bits of news, memes. It’s a slower pace, but I think in time it’ll grow faster. People migrate over occasionally, but there may be a critical mass moment when it’s big enough that lots of people start flooding over. Or it won’t and it’ll just fizzle out to nothing over time, who knows. For the moment it’s good enough for me to have replaced Reddit entirely.

As for things that are better: you get a lot more control over how you want to experience it. There’s no singular controller always dragging the experience down toward profitability. There are clients a-plenty, the api is open, you can control what parts of the network you see and which you don’t. It does take some effort, of course.

As for worse, because there’s no singular entity controlling the network, there’s going to be some very dark corners. You can block them (many will be blocked by individual server operators already), but they’re still there and they get to carry the Lemmy name and newcomers are most likely to experience it.

Just my thoughts on the subject, it’s been discussed a lot, I’m sure other people have quite different perspectives.
