People want free content with no ads.
This doesn't block ads. Everyone will see the exact same number of ads.
This also doesn't block normal and useful tracking. This blocks only the very most invasive forms of tracking which then enabled companies to recreate a person's web browsing history in almost its entirety.
I don't like that companies I've never done business with and never heard of have my entire browsing history. That is not necessary for free content.
Even if you don't care at all about privacy, there are more concerns. Trackers are wrecking the web. The following analysis explains it well:

Basically 10% of what he downloaded was content and 90% was everything else (ads, tracking, and code they are running on your device). In that example from 2 years ago, the Verge had 20 trackers going. Altogether there were 263 HTTP requests, which is ridiculous.
What should be a simple news web page took 30 seconds to render because of the horrendous amount of crap.
They are blowing through your data, which is a problem on limited data plans. They are executing code, which burns your battery. They are making hundreds of HTTP connections per page, which slows down your web experience and cripples the web on older devices and older browsers.
It's going to get worse and worse and worse unless we fight back to keep it reasonable. I just checked The Verge and now it's up from 20 trackers to 30.
I've actually gone to webpages that were so loaded with crap,
they broke and quit before I could even see the article. That's not good for anyone--not me, not the advertisers, and not the content provider.
Yes we can't all have free content without ads. That's not what is happening here. This is small push back from one of the least used browsers against some of the worst forms of tracking.
