Then I have no idea what you’re referring to by ‘what google is doing to android and tried to do to web’ because as far as I know, that isn’t relevant.

What I’m describing is definitively not antivirus. Antiviruses use heuristics (and known checksums of bad things) to scan processes/files/network traffic/system calls for dangerous patterns. They’re not doing real-time checksuming to detect system corruption or malfunction, they’re not comparing known system files because that’s complex and hard to do, and seems to be what the company is claiming here.

I have no idea what Google checksuming you’re referring to but as far as I’m aware that’s a not thing they’re doing to android and trying to do web. Everything Linux (including Android) does some amount of checksums at certain points because they’re useful, but not real-time process checksums. I assumed you were surely referring to them requiring that apps get signed by their certificates, making everything subject to their approval. Which is different from realtime checksumming for integrity.
