Works for me - I rarely go out (living in what amounts to the Garden of Eden will do that for ya) - and no one gets my data if I don't want them to.
BUT! Now let's look at why things are the way they are. Artificial scarcity of both IPv4 addresses and um, profits. No one wants to settle for the margin they can get selling you something just once, now. Oh no, we all have to subscribe to almost everything (I Avoid this like the Plague - and do without if I hve to).
So they have to insert themselves in the loop by owning a static IP and domain. Yeah, some of them are free NOW - how long before you get charged rent to even make your own home work? I'll ignore the snooping for the purpose of making this point. You're willingly handing over control via IoT and anything subscription model. Period. You might not like the eventual results.
You have been warned!
