Really? You maintain a 'blacklist' somewhere on Dropbox or so, and every time you make a purchase you look through who is somehow connected to it, and cross check your 'blacklist'? I think it's much more likely you're showing some internet outrage here, but when you actually run into it, you won't even remember a week later.
Yes I do maintain a blacklist. The main vehicle is: when I see something I find unconscionable from a company with I'll add an Adguard rule to block their domain name. It's hardly water-tight, but what is?
Your "I think it's much more likely" is a bit odd considering what you know about me (ie. almost nothing). "Outrage" is also pretty exaggerated. There are millions of commercial outfits out there in the world, the vast majority of which I'll never have anything to do with. There's a low bar for me to exclude just one more from consideration.
