Mastodon is a social media app, a bit like Twitter, but instead of one company owning the whole thing, it is made of lots of smaller communities that can talk to each other. You join one community, but you can still follow and talk to people on other communities, a bit like how someone with a Gmail address can email someone with an Outlook address.

Ignore me if I’m being stupid, but could you just not give it internet? A lot of TVs have high spec CPU/APU these days and complicated firmware, surely ability to update the firmware for these is necessary for patches/feature improvements. They probably think it’s silly not to include software if they can, but I agree the software experience is often a bit of a let down. LGs been good, but admittedly I block all telemetry on my network so wouldn’t notice any downsides.
