If you think about it, if it wasn't for the revenue from the advertising, TechRepublic would probably not even exist. Then all that beneficial technical advice would be lost to the masses.
Depending on which internet browser you use, if you happen to use Firefox you can get an Add-On called [b]WOT[/b] (World of Trust) which basically does what AVG 8.0 tried. It marks search engine results with a traffic light system of whether the links are any good or not.
As I said, AVG 8.0 introduced this function but it slowed any search engine results to a horrendously slow pace - WOT does not. If you try searching for RegTool (using WOT) get ready for lots of bright red signals.

What any other Peer has advised on TR is not for me to comment on, other than to say that if they don't have actual experience of using it themselves, they should not promote it to someone else.
