How is this for an idea - companies that provide links to a website that also can generate a preview, charge the linked site for the privilege of having a preview of the content shown. This shows that such things are valuable for the recipient. If Google had done that, then this proposed law wouldn't have a leg to stand on. Perhaps they should do this for other news sites now, that way it protects them from future laws like this being proposed in other countries. Being linked like this is clearly worth it to the publishers, as the law they support prohibits the delisting of the sites that the law applies to.

Second, how about having a way to add meta-information to web pages/articles saying what is okay to use as preview and what is not. This looks to me like the long term solution to all sites and services on the current web. As long as there is a single, non-specialized way for browsers to ignore attributes/tags/other info they do not use then it does not add complexity to browsers.
