720p is fine, but I’d prefer 1080p most of the time.
It mostly just comes down to bitrate. A 4k video at 1Mbps is probably gonna look like shit. My drone and my go pro shoot 4k footage at 60Mbps h265 and that looks amazing. But if I’m acquiring a fuck ton of movies I’m not gonna download that shit at that bitrate. As long as the video is like 1080p and 5Mbps or higher I’m happy. If the file size is >6 gigs for a movie I ain’t downloading that shit even if I can, and that’s with a 1gb symmetrical internet connection and a 30TB NAS.
Like my Firefox profile data isn’t encrypted and I don’t see anyone sweating over that. This stupid chat history not being encrypted ain’t that different.
