StackOverflow had this problem, too; various large companies would put "for support, ask on StackOverflow!" style wording in place, with predictable results.
At pre-AI scale, StackOverflow was largely able to handle this traffic-flow. It was a bit frustrating for everyone, but that was kind of the norm on SO. Ultimately, a lot of support questions did get answered and the AIs trained on that, so when it's not telling you to email journalists you can thank SO for the tech support ChatGPT gives.
> for support, ask on StackOverflow!
Just a euphemism for "we have no customer support". In fairness, it's a more helpful suggestion than just a customer support stonewall.
Some companies had employees monitor their company's Stack Overflow tag. I think Stripe did that. I probably benefited from that at least a few times, which, in those moments of need, would have been quite helpful.
