Yes and no. My unpopular opinion is, financially, it's no one's business until the same bag reaches a reseller, but also, it's everyone's right to have a view on something that's an Hermes fashion.
For sure, individually, their bag their business.
Viewing the fashion/styling more objectively, apart from the odd, old picture of someone caught mid-rummage, this trend seems to have been first popularised by SM influencers needing to flex the Kelly's Hermes logo for the shot, only visible when the bag's open.
Influencers may pose for a sec, but longtime carried full/heavy, it damages the bag, especially the handle. Anyone buying the same preloved later will inherit the structural damage. Birkins can be carried open like a simple bag, but a Kelly isn't designed to be carried the same way.
And from the style-history, it isn't a nonchalant, cool-girl look as could be attributed to a thrown around open B, but a loud-and-proud-luxury flex. Nothing wrong with loud-luxury, so long as that's the intended vibe.
