Pornhub and BlueSky have done similar in response to this legislation in Texas. Wikipedia and a few other sites blocked the UK to avoid being burdened by their Safety act. Pretty much every streaming platform implements regional geo blocking for licensing reasons.
I’ll be curious to see how things shake out in the long run given the current political climate.
Also, for the enforcement agency who is/will be tasked with checking things out here...do they know whether geo-blocking is valid method or not? Its a silly law, don't get me wrong...but if its enforcement validation mechanisms are not up to snuff, i wonder how things will play out - both here in dreamwidth's case and other folks in a similar boat?
No? Wikipedia is not blocked in the UK.
It may not be, if the law can be applied to them.
OTOH, may be sufficient to make it illegal to apply the law to them in the first place. US states do not have unlimited jurisdiction to regulate conduct occurring outside of their borders, but they do have more ability to regulate conduct of entities intentionally doing business within their borders.
