People will buy regardless, so pushing filtration isn't an excuse for contaminated oils, it's reducing harm, like a needle exchange for heroin addicts isn't promoting that as a healthy lifestyle.
Visible floaters are almost a blessing in disguise ( of course they shouldn't be there, this is a larger point) because if it normalizes filtering UGL gear, it'll ultimately reduce harm across the board, far beyond QSC. Most contaminants are below visible range and no UGL should be trusted in that regard, even if it looks clear.
Tracy is responsive to feedback, eventually, which gives us leverage over what he offers. That's better than "take it or leave it" which others practice with a smile. Bare bones customer service in exchange for rock bottom prices is a standard tradeoff with almost anything, I'd expect the hot assistant at the Mercedes dealership to bring me a nice espresso in the waiting room, while fatso with the spaghetti stain on his shirt at Tony's "buy here pay here" used car lot can't really be complained about when he rolls his eyes at every request. So yeah, Tracy handles business well at the bargain end of the market. $60 Test-C kits, if they deliver the quality promised is an achievement in this shortage environment. If there's a communist heaven, Tracy may get a spot for making life changing Tirz health improvements accessible to a lot who otherwise wouldn't be able to afford it.
None of this excuses the oils bullshit, a genuine health risk which you know well I call out at every opportunity via mockery to make sure no one forgets, but I'd be a hypocrite to not notice what they're doing right.
