Typically you will get sambatv or such installed, and technicians for whatever reason tend to click accept/approve during installations. Happened to me n my Google TV thing

Tbf I was talking about first-party Google TV boxes (Google TV Streamer and Chromecast with Google TV.) Likely not perfect for privacy, but not pure evil like built-in smart TV firmware, they support sideloading without time limits, alternative app stores (Flicky/F-Droid) and they're friends/family/roommate/partner friendly with support for DRM-ed streaming apps, Chromecast and pairing with the official YouTube app.

I chose one over the Apple TV because I knew I wouldn't able to stand any limitations on sideloading. For a while I was running a custom build of Wholphin with patched libmpv/libplacebo to work around a bug before the fix was upstreamed. A device without the freedom to do that sort of thing would drive me nuts.

What technicians? When my TV was delivered they pretty much just unboxed it and set it on the floor, not even being willing to help mount it, let alone plugging it in.
