Man, ads are great. They allow content to be targeted towards people that could potentially not afford the content and towards people that might not necessarily use the product normally. The world is already significantly divided by wealth. Assuming someone poor even has access to a service like Google, imagine if it was behind a paywall. Could they afford it? If not imagine how much of a life advantage someone wealt…
The whole point of ads is to convince people to buy things that they may otherwise not. That seems like the opposite of helping poor people. Also, if you are struggling financially, ad supported "content" is probably not a major concern in your life, and certainly not a solution to your problems.
A/ws even people struggling financially like to relax and enjoy 'content', should this just be a privilege of the wealthy? Without ads it seems like it would be even more so. As for being a solution to their problems, its not ads, but the type of services ads can support. Using a Search Engine as an example again, they are a way to educate and empower oneself. I used a search engine to teach myself programming and I now am a developer. While of course most poor people could never dream of doing such a thing, for numerous reasons. Making content only accessable behind a pay wall acts to strength someone's,without means, ability to compete in the modern world.
