I am going to see how it shakes out over the next few months. Generally, I try to only post buyers-beware-style posts if there is a substantial issue with a transaction, such as a seller taking someone's money and disappearing, not completing a transaction, etc.
In this case, I believe Paul/A9 have been remarkably good in terms of their business (I've made multiple purchases from him and have been very pleased with his products), but I strongly disagree with some of the ideologies and marketing communication that have come to light recently, and said as such on his blog as well in private communication with him (which was civil).
For the moment, I took down the promotional reviews on my website/blog, because while I think his products are fantastic, the interaction left a bit of a bad taste to me as well. I'll take some time to think over if there is anything else I want to do.
