Why does it have the Huawei services SDK inside of it?

They are not supposed to be but Sisvel claims they are.

Theora is an old and very inefficient codec. VP8, VP9, and now AV1 have succeeded it.

You just have to connect your phone to the same Wi-Fi network as the TV, then press the cast button in an app and select the TV from the list.

Because Chromecast is a Google service, you must log into a Google account on the TV for it to work, however apps only mode hides the home screen ads and myactivity.google.com lets you disable the tracking.

SailfishOS is heavily closed source and Jolla used to be linked to Russia with Rostelecom owning 60%+ of it.

Yes it does.

By any brand which lets you use HDMI devices without connecting to Wi-Fi. TCLs have better specs than most for the price and they have a Basic TV mode which doesn’t need internet.

It’s where the main devs have gone now after Revanced banned the devs responsible for about 80% of the code.

The main devs have moved to Morphe now and Revanced is mostly just merging in Morphe code in broken ways.

Systemd is open source so it can be forked to have features removed.

They don’t take such a job because they want to.

You shouldn’t talk to customer support agents like that. They’re not responsible for the actions of the shitty company, and you are giving them a bad day for no reason.
