It's not just common tech, it's made by the same people. It's not independent. Full stop.
And even if the question was "Does IPFS use/depend on a blockchain?", the appropriate answer would be "no*" or "no, but" and then something that mentions filecoin.
Let me put it in another context, would you say Brave has a blockchain? I'd definitely say it does.
Heck, even Bluesky uses some IPFS tech. Does that mean it has a blockchain? Of course not.

I don’t use Brave, but from a cursory glance I think probably yes, it “uses/depends on” a blockchain for some functionality.

Can you show an example where that is the case for IPFS?
But one of them is directly tied to it.

It's just a web page, the actual browser functionality doesn't depend on it. But maybe it wasn't the best example.
