@moshtodon I'm not a native English speaker so I might not say things as they should ^^
Well advertising is a way to get money when you only look at the income, but it's not when you look at the outcome too.
Fist, advertising is always thought to bring lot of money but in fact, it doesn't get that much. For example for Paris' underground, deleting all advertising would only increase the ticket price for less than 5%, a few cents.
And sometimes it even doesn't get any money at all.

In Lille, the new digital billboards that were installed in the underground doesn't get any money at all to the metro service and thus doesn't reduce the ticket price to the users. We've managed to get the contract between the metro service and the advertiser stating this fact.

The second issue is that advertising cost us ,as individual and society, a lot of money.
The company that pay to get ads everywhere aren't running a charity, they want their money back. And they get it by impacting their advertising budget on the product price. We're paying for advertising every time we buy something from a company that use advertising. For example for cars it can go up to several thousand euros.

And it cost us as a society by manipulating us in buying stuffs we don't really need, costing money but also impacting our environment, minds (by always showing the same kind of fit white people which doesn't represent the body that everyone have).
We think that public transport should be paid by our society and also that if those company that pay advertising would pay they taxes, we wouldn't need advertising to get extra money in the first place.

I hope it's clearer now 🙂
Feel free if you have any extra questions

@RAPasso I'm sorry I don't fully understand. I don't see why would increase that little the price of the ticket if we are paying these ads that much. What's the real price of an advertisement?

There's 5 subjects here:
A. the company who pays for theis products to be announced and may gain in clients and sold products
B. the potential clients
C. the people who are not interested
D. the company who puts these ads (in this case, the metro).
E. Rest of society

How impact them all?

@RAPasso and thank you for your time and responses ☺️

@moshtodon No problem, it nice to do it in English too. But it's also harder and mastodon may not be the best way to do it ^^
I wouldn't count 5 subjets. I would merge B and C because we all buy product from a company that use advertising as most of the m use it.

@moshtodon
I should have explained how the advertising industry word to begin with, it would have been easier. In the case of the metro, it can be summarized to this :
A : the company that want its product to be know and is going to pay someone for this
B: the company that is going to design the ad
C: the company that is going to lease a billboard in the subway to put the ad in
D: the company running the metro service that is leasing space where to put billboards

@moshtodon

The things is :
A: doesn't want to lose money that B and C are costing him so they're going to charge their customer extra for their ad budget
C want to make a profit so his going to charge A more that what he's paying D
That's because of this and B that advertising can be such a huge part of a product price
And finally D is only getting a small part of what C is getting, that's why it's can be cheap to delete all advertising and get ad free public transport

@moshtodon

I feel like it would be clearer with a drawing ^^
Hope it's a bit better this time 🙂

@RAPasso if what happens if what you say, then alright, but I think you're assuming a lot of steps. For example, I agree that A doesn't want to lose money, but it's an inversion so it can just assume the risk without making anyone else pay for it.
