Chris,
There was a spate of soul-searching and navel gazing among wine writers maybe 10 years ago or so, that led to some fairly ludicrous reactions; journalists declaring a baseball cap they'd been given on a visit to a winery as a gift that must be declared. I never entered into that virtue signalling then, and have no intention of doing so now.
I've stated pretty clearly that I do not review wines for payment, which has been the case for 28 years. Yes, I review wines from sponsoring companies, and I try not to let the relationship influence me. The special treatment they get in return for sponsorship is that I prioritise tasting their wines if I have a lot on my bench to work through, and that I sometimes highlight sales or special deals they have here on the forum. That's about it.
You'll have to ask others how sponsorship or advertising affects their editorial.
