Isn't this actually an ongoing issue on eth? Vast majority of wallets are web-based so ISP has a record of every address requested by the IP address
when using most of the altcoins such as etherum users have a lot more issues to be concerned about rather than their privacy and their IP address being recorded. that is why we see a lot of web wallet usage, no PGP verification or even existence of it for desktop wallets either. and a lot more.
They do at least allow hardware wallets to connect to the site (on desktop) which is good.
I agree it's a shame there's no full node version afaik...
The wallet you use can certainly get your ip but all your isp will know is thst you've connected to that wallet and not the actual address you've looked up/sent to.
