Rule-based ad blocking limited to 30k, as stated in the article. That's why people are upset.
Except that list really is just bloated with rules that don't do anything anymore. > We measure how EasyList affects web browsing by applying EasyList to a sample of 10,000 websites. We find that 90.16% of the resource blocking rules in EasyList provide no benefit to users in common browsing scenarios.

Part of the point of an adblocker is to protect you in uncommon browsing scenarios. This is almost like saying that a malware list is bloated because some of the hashes its storing are uncommonly downloaded. Having as close to full coverage as possible is important.
It also opens up an attack vector for advertisers that they absolutely will exploit. With unlimited rules, there's no reason for ad networks not to use a few domains and serve their ads from a few sources. With a hard limit, there's a strong incentive for networks to collectively try and flood the lists with tons of different domains until we run out of room to include all of them.

This has been the number one complaint about the proposal from day one. If at this point the Chrome team still hasn't decided to tweak the limit, I just don't see how there's not gonna be any new argument past this point that anyone can make to convince them.
