I have a bit of a theory about this; I reckon it is symptomatic of modern hyper-consumerism.
It was an odd comment that a male friend of mine, who runs a masculinity project, made about hobbies for men having a culture surrounding the acquisition of "gear" that made me notice something about uncool hobbies vs cool hobbies.
Pretty much every hobby that where you create something or produce something tangible and material from lesser elements is generally perceived as "uncool", so knitting, crochet, pottery, veg growing, airfix kits, model-making, leather-working, woodworking -- even to some extent, baking.
Whereas hobbies where you consume significant elements to produce something less tangible and material are seen as "cool" or acceptable. Cycling is a perfect example of this, as is snowboarding, golfing, vinyl acquisition, shooting, gaming, playing an instrument etc.
So ... creation = uncool: consumption = cool.
Again, hobbies where you create something for other people to enjoy tend to also be perceived as uncool, whereas hobbies where the benefit is solely for the self are seen as cooler.
I think this is all basically a cultural dynamic of late stage capitalism that wants people to consume, rather then create ... and wants them to consume individualistically, rather than provide within community.
I also believe one of the subconscious consequences of this attitude towards "creation hobbies" is to radically disempower ordinary people and stifle understanding and awareness of just what, say, a jumper in M&S actually signifies.
I knit, and it never ceases to hit me when I walk into a knitwear section in a store just what is behind all those rails of cardigans: the amount of yarn, the amount of work, the mechanisation required for mass production, the energy needed to create those machines, the wages of those operating those machines, just how long it would take a human to handcraft those garments.
As a result, I am very careful about purchasing new knitted garments.
But global capitalism doesn't want us to think about those things. And I say that as someone who isn't an activist.
