Isn’t the issue that Google links to websites and then reduces their commercial viability by showing summaries in search pages or by having their AI present the data without letting the website get the traffic? If so, I think a link tax is justified. At that point, Google is creating value for itself by removing value from others so it seems fair to me. And we don’t need the law to be perfect - let’s just make it app…
I disagree, a "link tax" is the wrong choice of response, and incredibly dangerous to a free/distributed internet: Once it exists in principle its scope will not remain limited to affecting only big unsympathetic search-engine companies, it'll start affecting other sites (like, say, HN) and get abused to deter critics from pointing to the things they want to criticize.
If any source-page with a link is "summarizing" way too much about the destination... well, then there's already a mechanism for that: "Sue them for copyright infringement."
Right now things like titles and brief summaries and whatnot are clearly fair-use, but that's not guaranteed to be a defense against some future "you can't directly point at my page" law.
