This could also be another reason. This was a worry of mine when I first looked into monetising sites, but I ended up giving it a shot anyway, but despite AdBlockers being a thing; I am still able to make something.I think it could be due to the fact that ad-blockers exist and a lot of people use them. So maybe some people don't use adsense because they don't think people will click on any of their ads due to that? Idk, just a guess. It could be various other reasons, but I think it's a mix of many things, including adblockers and other things.
I think Adsense is the first choice for people who want to monetize their sites. I use Adsense and I see a lot of people using Adsense on their sites.
