Also their wifi got a “friendly wifi“ page, which says not… not that it has no captcha portal (it has one, which let's you rate your train temperature – fair enough – and – not fair enough – asks for why you are travelling…
Anyway… the #friendlyWifi initiative seems to be about yyeah, adding internet filters to your #WiFi lol… they even have a test page and collect donations – just why should I donate for broken internet filters? https://www.friendlywifi.com/
