Corporations have locally-defined privileges and exist by, and at, the will of the people where they reside. Governments can change what those privileges are at any moment, for any reason—or no reason at all.
If we don't like what Google is doing, we can simply write laws regulating it differently.

Hint: ongoing legal debate, i.e. it's up to government to decide what "corporate personhood" means—exactly what I am saying. It's up to government, not "inalienable" or "natural" or whatever.
It's a purely legal question whether trillion dollar corporate mega-platforms with billions of users have the same regulations and responsibilities as widows and orphans. We don't have to let the Googles and Facebooks and Amazons and YouTubes of the world trample on basic human rights "because ackshually, corporations are people too." Certainly nothing about the 14th Amendment requires it.
