I worked in a few AdShops for few short projects when I had to leave electronics for some time after my last employer in Canada was unable to secure a new work visa.

All and every were very very aware how adblocks can block double digits of their revenue with each new release, and it was considered an issue of existential importance. C-levels had weekly conference calls on dealing with adblocks.

In one of those companies, a senior was calling Google, and was pretty much receiving directions like "you can get around this block if you randomise this part of URL," "next months we will change this and that API, this will give you some breathing room."

Google is well aware of UBO, and for years tried to covertly subvert it.
