Just because Google built something valuable that doesn't mean the government should take control of it. This line of reasoning also leads to the government taking over YouTube and changing the rules there due to how "important" it is.
you're not making a good argument for privatization lol
The things mega corporations built could be even more valuable (for society) if they didn't intentionally restrict for their own and their shareholders' benefit what you can do with them.
"Regulating" also doesn't mean "taking control".
