C# isn’t exactly compiled, at least not into machine language. It is transpiled into byte code that is run on a virtual machine that on turn is an interpreter/JIT-compiler.

Depending on why someone is asking for a compiled language that may or may not be a problem, because to the one writing the code it looks like a compiled language, but to the one running it it looks like an interpreted one.

And which country are you from that you think you are entitled to throw the first stone?

Unless you actively pay attention it’s very easy to be logged into some Google service without noticing. At least I wouldn’t be surprised if chrome background services kept me logged into my work Google Mail account and kept tracking my IP.

The biggest question is how meaningful the IP alone is. I don’t know if VPNs assign people individual IP-adresses or if there’s some kind of NAT in use where people share an IP with translated ports. If the information is “there’s this individual VPN-user and we need to connect them to a name” then you shouldn’t use (the same) VPN for everything, but if it’s just “there’s another request from the same VPN” then it’s fine.

I don’t know. A VPN simply replaces your IP with one from their network, but you still have one IP that identifies you, right? So if you are using one tool to access YouTube while being logged into Google on your browser, doesn’t that defeat the purpose of the VPN? I mean if Google just stores the IPs that were used to log into accounts they can simply look up who downloaded their videos, right?

Can you elaborate?

I doubt that this move has made them much more “safe and controllable”, it just means that they depend on a different system. I mean as soon as a bug pops up in their software the rest of the world will be fine.
