There is no incentive for adding false positives to lists of malicious websites.
Chrome is big enough that a website owner can't afford a false positive on their malware list, just like they can't afford to have all their email end up in spam for all Gmail users.
Due to their near-monopoly Google also has no incentive to avoid adding false positives to their blocklist - provided they don't accidentally block high-profile targets. And if a CxO is screaming over your shoulder that your website has been blocked, arguments about "false positives" aren't very compelling: they'll just demand you move off the "shitty basement provider" and switch to "proper hosting, like the Google Cloud"...
that whiny bullshit about somebody elses website? you dont have to rely on a website or app. either you need their monopoly because you cant do it yourself, or you have options.... in both cases the whining is not needed
