I wouldn't post racks on tiktok either. The average user are pretty young and easily influenced by some of the outrage videos out there who give advice against racks whilst having sick and dead snakes, keeping them in fish tanks with little places to hide, and practically no experience.
I'm with Armiayana on this one. I'd love to provide a huge enclosure for every single animal that wants it some day, but some absolutely don't want it and would get sick in a large enclosure. One of mine I can't even upgrade to a larger tub because he refuses to eat and stays in a hide the entire time no matter how long I give him to settle in or how I clutter up the tub to give him extra cover (he's also one I have to feed slightly undersize meals more often because he is even terrified of his f/t meals). I'm going to keep trying because eventually he will accept it, but for now he's in a smaller than ideal tub and it's very much his choice. I have boys half his weight in a larger one and they are fine. No two animals are the same. Most people wouldn't like being stuck in a small space, but some people are terrified of big open spaces too.
This whole issue is why I have stopped trying to help struggling snake owners on reddit. Every time I give them solid advice on how to get their brand new BP to start eating, I get downvoted and attacked by people, including mods. It really stinks, because I care about the animals and want new people to have a good experience, so I really want to help, but they aren't going to follow my advice when every other person on there insists I'm an animal abuser and no snake should ever be kept in a tub no matter the circumstances, and tells them BPs need 70-85% humidity and 95-100F hotspot.
