Some sites certainly do present the only options "accept or go away", it slightly more subtle "by continuing..."¹.

IIRC this is against both the meaning and the letter of the law, but that is not practical to properly enforce so they get away with it.

the worst are accept or pay. i found it especially annoying to see that on a site like heise.de who should really know better.

There is at least some honesty in pay one way or another. The ad industry is so very rarely even that honest, that it is almost refreshing.
