I read the original post in this 19 page thread and listened to the audio posted.
There are a couple of things. First, based on the comments in the audio, the wet shaving community doesn't want negative feedback on artisan products. The speaker said that people get ugly emails, have their Facebook page deleted, etc... I always think about my audience. If I were Mantic59 or someone similar and I know that my followers don't want anything negative about artisans, then I wouldn't post any.
Also, most of the time, it isn't what you say, rather it is how you say it. The other day I did a review comparing and artisan, OneBlade and the razor blade they use and compared it to Gem. I scored Team OneBlade much lower on a specific attribute because of the amount of glue on the blades. In my explanation, I made sure to say why I gave a lower score and also acknowledged that many folks aren't bothered by the glue.
I wouldn't post a review on an artisan that wasn't true. I might decide not to review an artisan if I couldn't give a decent review.
Also, most products have a place and fill a need. I posted a review on a website not too long ago about a $5 puck of shaving soap from one of the wet shaving vendors. They are a smaller one, so are more in the artisan category. It's performance was such that I threw it away. In the review, I didn't say it was junk. I said that it is great for those on a budget. I acknowledged that it didn't perform as well as those costing 3 or 4 times as much and that folks could decide which best meets their needs.
There are plenty of shaving products that none of use would want to use - the cheap stuff that has been around forever. While we prefer higher end products, some of these others have been around for a very long time and continue to sell, thus there is a place for them in the market. Rather that bash them, I would talk about where they fit.
