Custom pricing feels like buying from a shopkeeper with no price stickers. You expect to get charged according to what he judges you can afford. It removes the value of being able to rely on all the other customers to collectively decide if the price is fair or not. That means every customer has to individually evaluate every price which is a massive waste of effort.
This is one of the best things about living in the developed world: most things are bought without haggling. All of your most stressful and miserable transactions -- buying a car, booking a flight, tipping a server -- lack a fixed, public price. Dynamic pricing based on digital surveillance is a huge step backward.
What reseller doesn't buy tickets when you book? They get paid when you buy, why would they refuse to buy?
I very rarely get shown ads.
I ran AdBlock Plus for a while until I discovered that it runs as an open proxy, allowing anyone on the same wifi network as you to fetch content through your phone.
In combination with a VPN client that routes everything over the VPN, I considered that an unacceptable risk.
Likewise, I've noticed a similar behaviour with ads on youtube. If you always click the skip ad button, you'll always get the 15s unskippable ads, or 30s ads. But when I stopped for a while (because a lot of the channels I watch are solely supported by them), YouTube kept pushing the line until it was showing 5 minute ads for 10 minute videos. So now I skip them again to avoid the gradual creeping increase in ad length.
