I'm not sure I understand what you're trying to say here. Going to Google's website or looking at Chrome documentation is a lot different than signing a TOS with them.
And Chromium is Open Source, so I don't need to sign a TOS to test V8 changes or get access to Chromium features.
The only reason a TOS is coming into this is because Google artificially inserted one in front of an origin trial that realistically should be handled based on some kind of request header or at most as a signup form with a DNS check for owner verification. None of that should require a legal contract or Google account.
