Yes, but which one do you think is censored/manipulated first?
There are times, when it's better to use something not that popular ;)
Couple of other arguments: The internet is built around decentralization... now all people use the same resolvers. Great. It's good to have proper alternatives.
Why do you assume that you can withstand government censorship longer than Google? I'm really curious - sometimes size is good, sometime it isn't.
Everyone is on Cloudflare anywho.. so much for decentralisation :-)
