Do you think ads are ethical? For a relevant example, how about an Apple ad that successfully uses emotion to convince you to buy a Mac instead of a Linux computer that would better suit your needs at a better price hypothetically?
Fair enough! I stand on the side that the current ad landscape in the US gravitates towards convincing us to buy things we don’t need and consume more. And normally using manipulative tactics. For example, ads in the car industry that sell a lifestyle that convinces people to buy large pick up trucks they don’t need at costs they can’t actually afford.
There is an implicit agreement that using those websites (for free) means you watch ads. I think: if you don't agree with that, then you shouldn't go to those sites.
We complain about "enshitification" -- but then we take away all potential sources of revenue (and refuse to pay). So the only companies that can provide "free" services are ones that are already monetizing you in other ways.
