The complexity of the patch isn't the issue, it's keeping up-to-date with the upstream code. This can be done but it requires constant work, discipline, and it probably would need funding.
But the worst part is that it sends the message that we as a community will tolerate megacorps injecting telemetry tracking into our compilers, and our response will be not only to stay in their ecosystem, but to do extra work for them to keep us there. That's not the the message I want Google to hear; I want them to hear us tell them where they can take their telemetry and shove it. We do that with our feet.
