It's strange that doing potentially-dangerous things with technology is frowned upon so much more than doing 'conventionally dangerous' stuff like base jumping, huge tricks on bikes/skateboards/snowboards, free climbing, and so on
But folk generally aren't mad with about things the Mythbusters' did, even though they could have been dangerous, because they were presented as dangerous. Folk have gotten into competitions to fill their backyards with the most foam they can -- which can be dangerous. But it's generally presented as that and they talk about the heat generated and such. Those sorts of things are generally presented as entertaining not a way to get around an expensive medical system or good idea.
Or phrased differently: there are no people with broken bones and insufficient funds looking at skateboarders and thinking: "I should do that, because I live in a nation without a propper health care system"
Also perhaps a dangerous skateboard trick is less likely to harm anyone else but oneself, whereas an engineering disaster can catastrophic at a range
I watch a lot of car stuff on youtube and I wince ever time I see someone use an angle ginder without gloves, or worse the blade shield.
It's a lot more common to go turn on a power tool and rip a finger off than to do a bmx jump, or build a killer robot or some such. There's a degree of normalization of deviance there.
Edit: why the downvotes?
As a noob, it’s more like putting on a blindfold and wandering across 101 at 8pm for a few minutes.
Skateboarding for noobs is much safer as it’s more on the broken bones side than fatalities.
It's like how stabbing yourself in a random spot on the torso with a knife would be (in my estimation) more frowned upon/antisocial than playing Russian roulette with a six shooter.
