I believe @eaton has ranted about this before, but just got stuck in the quagmire of trying to find a user manual for an old machine (in my case a Husqvarna Viking 250 sewing machine, probably about 30+ years old)
Husqvarna site, despite being fairly well organized and having a download button for the manual, leads to a page not found.
Pretty much the rest of the search results are pages filled with malware or inviting you to pay $5-10 to be able to download it.
