Not just their users. My org got pitched stackoverflow careers and their private knowledgebase around 2019. We were somewhat interested but found it too hard to work with them.

We weren't going to be a huge contract (~100k/yr) but the tone was very much "conform or fuck off". I think the sticking point was that we were offered 1x permanent careers ad in North America and 2 in Oceana, and we wanted 3 in Oceana instead.

I've had a similar experience the couple of times I've asked or attempted to respond to questions (about software I wrote lol) - grammar and framing seemed more important than technical information/a solution.

N=1 anecdata ofc, but I'm not surprised at their demise
