anythings capable of it, but the companies behind the (premium) boxes have less of an incentive. While theyre all capable, its a matter if you have trust in them. At least for the Shield TV for example, go download a shield tv rom if you really don’t trust Nvidia. If you are paranoid that they all can do it, than any smart device can do it because its connected to the internet.

this is why you get a separate apple tv/android box and not connect your tv to the internet

a couple of reasons, some being that 1, ip addresses are limited on the internet, and making it free would instantly fill it up. another is that there is still some work involved,because once you register for a domain, internet service providers and DNS providers around the world need to also add your newly established domain to ip to their DNS so that people get redirected to your domain correctly. the domain endings also have a cost attached to them due to popularity and who is allowed to hand them out. e.g country related domains (e.g .kr for korea, .fr for france has their reasons to charge or without handing a domain out, but some countries may get lucky and happen to have a domain thats desirable (e.g Anguilla has .ai) and thus will charge more

you also want to prevent domain name ransoming. if domain names were free, there will be people registering for all domain names to use as bargaining chips against a person or company similar to social media handles

i meam the payment for a domain name is kinda worth it. as well as a functional vpn
