A lot of well-researched deep technical dives I read are from non-commercial hobbyist sites, academic papers/reports, or blogs ran off the back of a company with some product/service to sell (like Raymond Chen's The Old New Thing, or malware investigations from antivirus vendors). Would even say that ad-supported articles commonly link back to one of these as their source.
