I have a mild level of hostility towards their brand due to the level of pedanticness on Stack Overflow. I think they've fostered an unwelcoming, hostile and elitist community that acts brashly to shut down legitimate questions, with a high rate of erroneous closings. I think the harm of letting these questions play out would be close to 0, I do not buy the argument that they're making it easier for folks to find the one canonical answer to each question.

I think there's only so much oxygen on the 'net for a help site centered around programming. I think to some extent it's a zero sum game and we've been stuck with the local maxima of Stack Overflow, where the nature of social media network momentum has prevented a competitor from forming and overtaking them. I don't necessarily want them to fail or anyone to lose their jobs, but I am happy that LLM's have arrived and replaced my usage of their site. I'm sure a lot of folks love StackOverflow, and it does provide real value, but I'd bet a disproportionately high number of people feel similar to me because of the way they operate that site.
