Hey, I'm the author of the post. I did not post it to hacker news, but to the r/rust subreddit, where I think people had more context, and more reasons to be interested in it. Someone else posted the link to hacker news.
The title (which I indeed wanted to be a good catch phrase) was not meant to be an apology. English is not my mother tongue, so I may be misguided, but I meant "sorry" as "I am sorry about the state of affairs", not literally "I apologize to you, the sqlx library".
