Honestly the way the internet is going do you need access to the majority of the internet? I feel like its pretty dead as it is now already.
Lemmy will still work because we mostly use Firefox, and i bet the same will hold true for many others.
Basically the moment mainstream internet becomes google only you will see nerds build new websites specifiably to cater to the non google crowd and i trust random internet nerds a hack of a lot more than a monopoly corporation.
BRING IT ON GOOGLE!, YOU CAN INITIATE THE PUSH TO CREATE A NEW BETTER INTERNET. ^Create demand for freedom trough your suppressive enforments^
