As a user who suddenly knows nothing about uBlock the ad blocker, are you going to trust an addin with 2k installs and 4.3 stars, or an addin with 30m installs and 4.7 stars?
Install base can be informative when choosing.... anything, really. In many people's minds something that is used more is better in some metric, be it performance, reliability, price, et. al.
