It's absolutely nothing to do about moral judgements or being po-faced, I think that's quite an unkind thing to say.
Well I think it’s quite unkind to invite people into your home and act like they’re welcome, but then go online bitching about them because they’re not up by some imaginary deadline.
That's unfair. How do you know they are not genuinely welcome? Why would anyone go to the trouble of inviting guests in the first place and do all the extra work that it entails if they did not have genuinely good intentions?
And one person's "bitching on the Internet" is another person's "answering the question the op posed and joining in the discussion" if that's OK with you?
Also, the sentence you quoted above had a context; it was in response to a pp or pps suggesting that those with dc were adopting an air of moral superiority about being up early, which is unfair, because those with young dc don't really have much of a choice about it and what all of this boils down to is guests and hosts alike having consideration for one another and their respective situations.
Having hosted a lot for years and years, some guests come and have the attitude that their presence doesn't make any difference to the running of a household, and of course it appears like that if the host is doing a good job of hosting!
In reality though you have probably altered your plans a bit, maybe collected them from train station/ airport and delivered them back, planned expeditions and interesting day trips, planned the meals, shopped, cooked and washed up more than usual, made beds, cleaned bathrooms, kept the dc out of the way when their schedule has been disrupted and they are excited about guests being in the house etc etc.
That doesn't mean you don't t really appreciate them being there and appreciate their effort in travelling to see you. Or that you don't enjoy spending time with them. Of course you do! And you genuinely want them to enjoy their stay too.
The two positions are not mutually exclusive.
