Temu is insanely popular. Don't underestimate this. Yes, it's pure crap, but people buy it. They earn bucks.
Meaning, it's not a valid argument to say it's crap, and then it's not a problem. Temu is a problem.
But then we have to start another discussion about the free market, because then Temu is valid.
Then what? Legit question, I don't have the answer to.
