They’re “complaining” about unique qualities of their art being used, without consent, to create new things which ultimately de-value their original art.
It’s a debate to be had, I’m not clearly in favour of either argument here, but it’s quite obvious what they’re upset with.
Might just be my experience but in the UK at least, it’s almost exclusively women who drive cars like this. Men more commonly drive vans and super large vehicles to be fair, but specifically larger than necessary, non-tradesman style cars (Land Rovers, very clean, empty pick-ups etc.)
