That is not accurate. If you went head-to-head with the Standard Oil Company they would send a guy over to blow up your house. The East India Company was based chiefly on genocide and high seas piracy. All this yip-yap about Google being a ruthless monopoly on a historic scale is completely ridiculous.
As for the Chrome login thing, being logged in on Chrome does not in any way shape or form alter the way in which Chrome interacts with non-Google sites or services. So I don't see how it is an example of how Google exercises control over the web. Certainly not in a world where I need only drag Chrome into the trash can to switch browsers (and, indeed, on a computer where Apple constantly exhorts me, in a way I cannot disable, to switch to Safari instead).
It shouldn’t be a surprise that the company all-in on the Web has a solution for every part of the stack. It might be a surprise that they open source so many things but that’s a pleasant surprise. Every thing you mentioned has a replacement from someone else so I don’t see how you concluded “control”. And finally the great majority of Google’s backends are written in C++ not Go.
gRPC is not "typed" in any substantial way. You wan use any payload encoding you feel like suits your worldview. Protobufs happen to be a common choice.
Proto encoding makes the unfortunate choice of more-bit variable-length numbers which are hard to decode. JavaScript engines and browser all have very well optimized decoders for the unary length-prefixed variable-length numbers (i.e. UTF-8). So you can imagine how an encoding very much like proto but with the proper style of varints can be faster.
Generated code size is a huge problem of all protobuf-supporting languages, not just js. Code size issues on Android have constrained development of the official (google) protobuf libraries in various ways over the years.
