This place is sponsored by a combination of our host, Amir, who pays for the site and all the test equipment, and a fair bit of the equipment being tested, which he then eventually sells off, if he can be bothered.
The rest comes from us members, paying an annual/whenever amount to keep the site going, and especially those of us in the US, may lend our equipment or have new purchases drop-shipped to Amir for testing before we even get our hands on them.
There is no advertising or behind-the-scenes industry sponsorship as far as I'm aware, so whatever opinions/test reports/criticisms/praise are on this site are the views of the posters.
What agenda individual posters may have is debatable, but anyone shilling or decrying any product is fairly soon found out, so it seems to happen far less on this forum than on any other I know.
If there's an criticism I can levy at this forum is the occasional lack of rigour on test reports which then need correcting, presumably due to the perceived urgency of getting the reports out, and my personal bugbear of products being criticised for being (often far) less than SOTA, whilst nevertheless being quite good enough for transparency.
I've come to rely on this forum far far more than any other which is either in thrall to advertisers, or the Mods' egos. Neither of which is evident here.
