You're quite right on the nail except some are already suffering from climate change and the poorest countries will be the most unprepared to try countering it, not to say countries that will be consumed by the rising sea levels too. And the richest countries causing the most damage goes after climate activists instead of discussing more social justice, we can already see some media outlets try to sham some of them too.

Thanks!

I've used SingleFile long ago before I started switching many softwares I used to more ethical/privacy-wise better ones and I never knew it was open-source that's good to know, thanks. Since then I have been using HTTrack for pages sometimes. I didn't know about WebScrapBook though, thanks for making me aware of it. I also never tried to save videos with softwares witj the purpose to save pages however I could make some use of these suggestions for other things, my goal is to automate it and while these suggestions are all good maybe not for automated synchronization with these platforms or other video sharing platforms. It's still very helpful your suggestions nevertheless, thank you!

Thank you for all the insights they're all helpful! I am taking affordability as priority but also sustainability so these are all good information for me to know to take a better decision on choosing

Thanks that's reassuring.

Thanks, I was only aware of being able to download auto subtitles from yt-dlp and downloading description into a text file. Is it possible to download comments too? Depending on what kind of video you watch, like if you are watching a video about grammar on foreign languages, sometimes there are people giving good advices in approaching it in a more simplistic way or easier to remember.

e: apparently there's --write-comments for that to save into a json file

I am aware of there existing desktop-first open-source like PrimeOS and fydeOS for low-end computer/notebook but since it'd only be used for that I don't think it'd be worthy having an extra device exclusively for that, if I end up having another use cases restricted to Android maybe I'd have the more reasons to try such approach. I'll sure keep it in mind though, I really appreciate your suggestion, thank you!

TIL of TubeSync, thanks, I'm looking into it!

Thanks for the input, I do occasionally read manga/comics but it'd not be a dealbreaker for me to compromise on it for a while

Kindle is very affordable but can you jailbreak non-Paperwhite Kindles too? I thought Kindles were very strictly hard to jailbreak while keeping it usable

For language learning there's Language Transfer (it's also open source)

Does Kindle Keyboard last long? Also since it's from Amazon and you mention the seas.. don't they lock you out of your device? I have heard multiple times of Amazon locking people out of their account, not sure if locked out of the device, just for misdetecting them to have books they didn't buy. My only issue with E ink would be black/screen only display but I could try getting used to it. The only other use I would think of possible issue but I guess I could resort to my personal computer to, is when reading a book/PDF in a foreign language with an open-source dictionaries of those you can click on words (I heard Kindle has that too though, right?) to view the meaning
