Yes, it’s a problem that something like that is insulting to publish.
I'm not sure. Times change, and things that were acceptable become not so - and vice versa.
It's not just acceptability. Jokes written even just five or ten years ago often fail to land on modern audiences. That taste in humor changes is neither morally positive nor negative. It's easy to look for deeper meaning in the notion that what once was funny now isn't, but often, there isn't a deeper meaning to find. Life is different now; so too must humor change.
When I re-watch comedy like ‘The Young Ones’ or many other funny series from the 80s or 90s, I don’t find it funny any more. It’s not that the jokes weren’t good and that I didn’t find it funny at the time, it’s just that humour changes. In that case, it’s nothing to do with the jokes becoming ‘unacceptable’.
I find Yes Minister funny now, and I'm too young to have watched when it first aired.
I used to find The Thick of It hilarious but now I find it a depressing reminder of how ludicrous modern politics has become
