I don’t think your vegetarian scenario flies. I would not expect to get any meat information from a vegan site. I would expect a search on Google shopping to bring back...whatever product I am search for. Though I agree it is their prerogative to do so, it just seems wrong and like you said annoying as h3ll.
I sent Google an email asking why but have not heard anything back.
Be sure to also ask why their shopping service "censors" info on vehicles and tobacco, as well as other products.
Truly, this is unfortunate, but hardly a sudden outrage. They get to do as they please.
It is not a Conservative value to try to "force" a private commercial entity to provide something they don't choose to provide. That's what leftists do.
Instead, we get to use another shopping service. Simple. There are a lot of other shopping services.
