Yeah but this isn’t as big a deal as the clickbait headline.

Use Pi-hole and block their domains

Sorta. I have some lg tvs and I’ve been able to dumb a lot of it down for their lg services by using a pi-hole ad blocker and adding the lg ad service domains to the blocker. This isn’t totally what you’re asking, but I think you could block even more with some testing.

Welp, I didn’t yet delete my account. But this did it for me.
