My home PC uBlock blocked 1.7 million ads since installation, my work PC 900.000. If I'm spending 0.25 second to decide for something, if it is important or not, that is 31 days (743 hours) of my time, in the last 4-5 years. That is a lot of time. The real time will be of course smaller, but I just cannot afford it to go online without blocking ads.
Its like 10% of the features of all pages.
And I have a blocker for all the social media. I really dont care, how many people 'liked' a stuff. I dont. Go away, I'm not part of the herd.
