I suspect this is the popular reason. Unfortunately, I think it forces ad blockers (which I use only for tracker blocking) towards heavy features. Eventually the choice will be between running a bloated plug-in or being tracked. I hope uBlock Origin will keep in mind that some people only care about the tracking.

Efficiency is a primary feature of uBlock Origin, it's not going anywhere, regardless of whether it blocks tracking or ads, or whatever else.
Just pick your filter lists according to what you want to achieve.
In any case, I fail to see the difference between ads and tracking, as I have often mentioned, ads are just the visible tip of the tracking/profiling iceberg.
"In any case, I fail to see the difference between ads and tracking"
I agree for most ads as they are implemented now but things like the common audible.com mentions in YouTube videos I'm totally fine with, that's how advertising was done for decades before the internet and there's no reason it can't still be done. Web page standards give too much power to the page author by default, if the things they use to track people had never been allowed by default, we never would have had this problem because no sane person would agree to them if asked.
It appears to have a very relaxed definition of tracker. For example, it let doubleclick.net through. All drop-in ad network scripts are trackers, regardless of what they might promise. I'm fine with people adding ads natively to their content so what I'm saying is I don't want my ad blocker trying to do something like analyses video on the fly to strip out native ads or examining text to find disguised advertising. What ad blockers do now is good enough for me and if a content creator gets too annoying with in-line ads, I'll just stop consuming it.
