The word "oof" affects a casual, breezy tone that is inappropriate in a professional response to a customer concern.

Yes that's casual. But how it that inappropriate? It's not a legal document.

Or it’s a genuine expression of embarrassment and anyone who would be bothered by that is an asshole. It’s three letters. Who cares?

it's insulting because it is attempting to minimize the customer's stake in the problem by appearing to be concerned and empathetic.

if they were concerned or empathetic, the issue would not have lasted as long as it has.

in short, it's disingenuous and it's an attempt to minimize the customer's concerns.

Do you have special crystal ball that lets you peer into another company’s dev processes? If not, who are you to claim people have no empathy? That’s not only a really dark view of humans but it ignores the possibility that they cannot fix it right now.

God people, have a touch of respect for our colleagues.

Probably Notion should not have put them into this situation in the first place? Maybe they should have been more clear on the issue they’re having so nobody has to make a guess? Shortly explain the details of the issue they’re having and give some timelines? Like mature companies do? It would be good enough for me if I were their customer but oof, who am I to suggest.

I have respect for my colleagues at other companies.

They lose it when they talk down to me. "oof, sorry about that, but this is not important enough for us to fix right now" is not how you keep my respect, when the functionality has been broken for months.

In my experience, it's mostly the Millienial developer who writes error messages like these and the Gen X that takes offence (probably because this reminds them of their condescending Boomer parents ;))
