This might actually be a good idea if it's just something parents can set in parental controls so that websites and apps can check it for parental restrictions.
They can be considered petty bourgeois, yes, though IMO "artisan" is more specific and useful, as @into_highest_invite@lemmygrad.ml said. A common characteristic of the petty bourgeois is that they seek to identify themselves with the "haute" bourgeoisie, which is what freelance photographers who employ no other people are doing when they describe themselves as "photography business owners".
I don't think "there is a class difference between those who are self-employed and those who employ others and describing both as business owners only flattens that difference" is a reach. Describing oneself as a business owner instead of a laborer when doing freelance labor is an example of the tendency of the lowest of the petty bourgeois to try to liken themselves to the "haute" bourgeoisie.
I am attempting to explain what OP said in the title.
people's brains are so addled by capitalism that people who take pictures of people's pets for a living will tell you that they have a "pet photography business"
You're right technically, what I really meant was that they were LARPing as bourgeois. They're not bourgeois if they don't employ others. Without being bourgeois, "business owner" is a technicality and the only effect of using it to describe oneself is that it (attempts to) liken oneself to the actual bourgeoisie (the LARP). They are freelance photographers, not "photography business owners" because they make money by taking photographs, not owning a photography business.
It's the difference between describing an occupation and LARPing as a "small business owner". Unless you employ others, it's just your labor and IMO describing yourself as a "business owner" in that situation is bourgeois mentality. It could be "I work as a pet photographer" if you prefer.
"I'm a pet photographer" instead of "I own a pet photography business".
"As long as it owns the person who wants the second worst car."
This thread is an embarrassment, I can't believe there are people on Hexbear handwringing about violence against settler civilians. Did Native Americans never kill colonizer civilians? Are we going to start condemning the Haitian revolutionaries?
Israelis are constantly pretending they live in fear of being killed by Palestinian "terrorists". Have they considered fucking leaving, which is an option the Palestinians don't even have? No Israeli children would be in a position to be killed in the fighting or held hostage if their colonizer parents hadn't put them there. These children are victims, but they're victims of their colonizer parents and colonizer politicians.
You want to talk about children being held hostage to ensure compliance from adults? How many Palestinian children are there in the open air prison of Gaza, where 2/3 of the population are under 25 years old?



Parents are already able to do whatever they want to their children's devices with parental software. What it would allow is for websites and users themselves to flag their content as not suitable for younger viewers, which might be more useful than the ad-hoc and probably more invasive client-side parental controls. It would also be useful in certain online communities where people don't want to be interacting (especially unknowingly) with children.
Anyway, this is all a ridiculous hypothetical because it assumes the reason this is being done is not evil, which is obviously not actually true.
