Wireguard, even though they explicitly mention it in their tutorials, doesn't have an allow/block list for me, so I can't allow the proxy network bridge. Curious those settings are gone. Too bad!
"authentication is not security," can you elaborate on that?
Your statement doesn't really overlap with my understanding of security, as "just access" seems critically relevant to how secure user data is, for example. Am I missing something?
EU servers might be worth something to some people, depending on where they are in the world. And while 190% is indeed "way more expensive", relatively speaking, it's still "well under" your goal of EUR 2 per month.
I recommend installing calibre web on a home server, installing koreader on the Kobo, and accessing your eBook library over your WiFi and OPDS.
Koreader is such a good reading experience, I never want to go back to stock firmware (well, except for the dictionaries maybe, those are better.)
