These kinds of declarations rarely make sense to me because they don't seem to model the issues in the way that I see them. I have dual roles: one as a person who writes a blog (a "content producer" in our present parlance) and as a user. As a user, I want my browser user agent to act on my behalf to display web pages, and I want my search agent to extract information from numerous sources and synthesize them with appropriate sourcing.
One could argue that my content production being a hobby lets me be pretty blasé about being intermediated by a platform. That is somewhat true. If I relied upon this as a living, I would probably also conclude that actions that harm my way of living are a war on "the web", though realistically any neutral party observing must conclude that if it is a war, it's one on my kind of participation in the web - content creation for the purpose of revenue / notoriety / some other reward.
As a user, I don't actually care very much for each website and its creator. The information contained therein is useful to me, but the heterogeneity of these sites is mostly an obstacle to the information. I am much happier when my search and summarization agents are able to accurately synthesize what these websites say, in so much as such a synthesis allows me to model reality more accurately.
So I could be convinced that this change from Google makes it less likely for accurate content to be created and that I'll be misled more often. But this is a tool, and my world-model will frequently be tested by reality. If the search-and-synthesis machine fails to produce useful outcomes, I will know. And I'll have to adjust the way I treat knowledge I obtain through it so that I don't get catastrophic outcomes. But that's the same already. I don't really know that Google's search results are not planted ones calibrated to change my opinion. And I don't know that they don't collude with the Internet Archive (with whom they have a pre-existing relationship) to make it look like their constructed consensus is real.
As a user, I have to make a lot of decisions already, and having to painstakingly read search results to synthesize them myself is far less useful than using an agent. So if there is a war on the web, then I am glad to join it, on the side against the web.
I...have to agree about siding against the web...An optimistic part of me sees this as a move that pushes in the same direction that the "web" has already been going in for a long time - preventing users from getting the right information in an honest and efficient manner, preserving their attention budget, and choice. Until now, it was through increasing the noise to push monetary incentives, and now it's by cutting the noise to push monetary incentives. Why optimistic: up till now, there was no single enemy, and it was hard to fight a (somewhat) disjointed system; now, Google is positioning itself to push things further to the worse, with them (and small number of other companies) being the clear target.
My hope is that this will help overflow the proverbial glass for an increasing amount of people and we'll start pushing back towards the "old" web before Google and ad networks have transformed it, or find new modalities of interacting more freely with each other, and the content.
It's not going to be a small or easy fight, though...to a large extent, it's a fight against the current state of capitalism itself, and winning back our attention, critical thinking and choice.
