If they limit the rate of speed it's technically limited which really makes me wonder how they legally can say these things. I guess it means in a lot of cases it's like Comcast where they also limit the data a month perhaps but dang.

They offer "unlimited" where I live, not "unlimited*".

Doesn't help when you still need a VPN to get rid of Telekom/Vodafones abysmal peering

And they have the necessary pipes to serve the rate they sell you 24/7.

Nobody has turned the moon into a hard drive yet.

It’s not unlimited. The limit might be very high these days, but it’s at most bandwidth times duration. And while that sounds trivial, it does mean they aren’t selling you an infinity of a resource.

Unsure if sarcastic but most ISPs will throttle and "traffic" long before you use anything close to <bandwidth rating> times <seconds in a month>.
