> There are about 144 million active adblock users around the world.

That is a small number of people of the total Internet population.

It's a bit surprising that you think an advertiser pushing ads is a suitable source for information about ad-blocking. Obviously they're going to say that ad-blocking is prevalant and that you need to run better ads to stop people running ad-blockers and oh, we just happen to be an ad company that runs that particular type of ad.

It was the best source at hand, if you have another study i'd be interested to hear it.

There's apparently 2.9bn internet users, so you're right that ~5% isn't a very big number in context.
