I find this argument very weak. Should communists not buy anything? Should anarchists not use roads?

When your political beliefs are at odds with the current legal framework, you have no choice but to compromise to some degree. That doesn't mean you don't actually believe what you claim.

My point was it comes from a entitled position. I'm not making the absolutist position, nor am I dismissing all advertising like OP, but these business models exist for a reason and that is why we have so many of our products online.

It's easy for us to use adblockers as the minority of technical users, but that's a privilege based on the other 90% still seeing them (which I personally see nothing wrong with and clearly most publishers dont want to poke the bear either).

Otherwise of course people would love to have everything free plus no ads. But ads built and paid for a lot of good things on the internet, which wouldn't have been possible had they all expected payment or other models.

I'm all for pushing Google et al to be less aggressive with ads and make the web more usable and not requiring adblockers in order to have basic performance. But I don't disparage advertising as a whole because I understand the tradeoffs.
