Is it "censorship" when they simply choose not to be the medium to communicate that data to you?
If so, that puts the entire search apparatus in the category of "censorship," since it makes opinionated decisions regarding what the answer to your query should be. Choosing to refrain from vending a Drive URL is basically the same thing.
Edit: I could see an argument that they're being a bad steward of other people's data if they choose not to honor share requests on content they host or choose to remove content they've previously hosted. In which case, I'm glad they're putting the fact they'll do that right in a public disclosure, and it is something people should consider when choosing Drive to host their content.
The search apparatus is exactly the target of those trying to implement censorship.
Six months ago saying covid-19 originated in a lab was verboten on many platforms - saying it on facebook or YouTube would get you called a purveyor of misinformation and the content deleted and and your account at risk.
Suddenly it turns out the people involved at the government level funded the work exactly, and they worked with these companies to define what was misinformation, and suddenly Jon Stewart is making jokes about it and these companies allow it to be talked about again.
If you don’t understand how dangerous the platforms that house our public speech banning some speech based on “misinformation” is you aren’t paying any attention. They have set up their systems to detect/downrank/remove arbitrary content and that will be used for political reasons - it already has been and quite recently.
We live in dangerous times and a lot of people are oblivious.
