The intative promises to be privacy-friendly with no tracking. Stating:

Your privacy is important. The WiFi4EU app ensures a private online experience with no tracking or data collection. Simply connect and enjoy free public Wi-Fi without concerns.

Will be interesting to see how this spans and plays out in reality. Looks promising too, did a quick scan of their builtin permissions and trackers and looks good too. (Scanning tool is called Exodus)

Forgive me for not covering 100% of this advanced topic in my 3 paragraphs on Lemmy...

Quite obviously the problem is not that you did not write an 560 page essay, but that you were misleading by basically saying "nah, it's fine, nothing could leak, everything is ultra secure nowadays".

If you purposefully steer your car off the road... of course you're going to crash. If you're going to expose non-encrypted things onto the internet...

did you just ignore a whole lot of points here? DNS, SNI? smb clients? whatever else? its not like I'm using HTTP. things are largely encrypted, the rest is out of reach!

Encrypted SNI (ESNI) / Encrypted Client Hello (ECH) exists... Cloudflare for example supports ECH, and they transit a LOT of data.

how many sites exactly support that configuration? do you need additional configuration for that in e.g. nginx? if so, most selfhosters probably don't have it, because it's talked about almost nowhere.

and is it finally enabled by default in firefox? will firefox just retry without encryption when the connection fails?

But once again... would be outside of the scope of discussion here. Yes... an ISP can make an educated guess of where you're likely to be going... and maybe even make a reasonable guess of what you could doing... But certainly not the details of it.

it is certainly in scope. the discussion is not about security and your accounts getting hacked by evil EU, but privacy and data mining, for which all of these is a treasure trove.

And this all ignores the fact that a random coffee shop isn't going to do full packet inspection to get this data to begin with. It's not worth it for them.

probably not the coffee shop but the networking equipment, where even cheaper models include some form of "smart cloud security"

The fact that I addressed some of these items literally line by line and you bring it up again as if I didn't address it tells me that you're arguing in bad faith. Have a good day. Find someone else to complain to.
