I’d say helpfulness, responsiveness and being friends are three different things, that can be overlapping or not.
I know some people who always respond and keep the conversation alive even though we’re not friends, and i can be ghosted for days by close friends, who i lived intense things with.
I know some people who helped me moving out even though we were just accointances, and i have friends who are lazy enough to avoid this, but i live spending time with them anyway.
These are very fluid for me, so i’d say to avoid worrying, it’s best to not expect a lot from people, and/or to try to find friends that seem to match your needs

I don’t know if you mean “used to” as in years before, but recently every time i saw people talking about Deutsche Bahn it was to say “lol Deutsche Bahn is having a problem again”, so it seems to me their reputation is not (anymore) the reputation of a reliable service.
