Consent is not the only legal basis for processing. This website in particular claims Legitimate Interest as their legal basis for Google Analytics. If you can support a claim of Legitimate Interest, then none of the restrictions specific to Consent apply. Starting with opt-in vs out-out.
As a layman I'd assume that if one site gets to claim Google Analytics as "legitimate interest", this would imply GA being fair game for any site, provided they don't do anything special with it.
The former is a lot broader then the latter (and the latter is a US legal term and means precisely nothing in the EU).
