why is this such a bad thing? it's not really any different from using a uuid as a user facing key, which basically everyone does.

and trying to protect your moat isn't automatically a bad thing. they clearly feel it's helping competition, so they're closing a hole. competition is good doesn't mean help your competitors.

I guess someone made a website which google crawled and adding a senf made uuid to it is like google trying to own it rather than just being a true search engine just having index to it.
