Re: No guilt at all
While I would not mind to contribute some ad revenue for my favourite site, it is definitely not going to be at the cost of using half of my CPU.
It's not the Ad's per se that are annoying but the amount of resources they take. Many sites become virtually unusable without some form of ad blocking. Either through the dozens of trackers and beacons or intrusiveness of ads or both.
So long as websites serve ads that ruin the viewing experience I'll keep blocking them without guilt.
