Signal doesn’t provide such open and easily found chat rooms.
It’s really much more a messenger (with group chats, but those you have to manually set up)
So it’s not an “open” place like telegram and with that not as attractive for advertising illicit services or products.
besides that, Signal is the technically much more secure variant. No discussion about it.
I recently got myself a Pixel 7 Pro. the preinstalled OS really tries to push all the Google stuff on you, which isn’t great.
but after a quick look around for 1 hour, I installed GrapheneOS and am very happy with it
although I’d really like to have a Linux smartphone. but there seems to be none with good hardware…
With a HDMI-CEC Adapter it could be, that you can even use your TV remote to control your PC/Kodi
Not sure if your TV supports it - as I’m not much of a TV guy and don’t know, if you need any higher standard for that
But I’m quite happy with an old laptop + Kodi, linked up to my TV. Works quite well.
Only have to go through some audio settings for modern movies, where the sound mixing is usually not nice for dialogues…
