It sounds like most are not liking it because of some potential future abuses rather than what it actually is?
If I, potentially, wanted to abuse a system, I’d probably come up with a way to modify that system such that I can abuse it, but with a plausible explanation as to why I’m not actually going to do that, so that others will agree to it.
But let’s assume, for the sake of the argument, that Google and/or the people who wrote this are actually acting in good faith. That still won’t stop other large companies like Microsoft, Apple, etc. or even future Google employees from abusing the system later on.
Yes, the potential for abuse is the big deal here. And you know humans, if it can be abused, someone will try.
