1) How will it cost to read the newspaper 5$ in Rwanda? That's the price of a monthly subscription in Germany.

2) If said people can't afford 5$/month how will they afford the stuff ads are targeting them to buy?

This is what concerns me most about ad blocking.

"In a world without ads, people will just pay their own way" is elitist thinking. Most people online have nothing of value to exchange except their attention.
