Mental Outlaw does some cool videos about software privacy and security topics (interspersed with videos from his farm) and there is a lemmy community for it I think.

The Volgun does great, dramatized readings of SCP Foundation articles

Techlore is also software privacy and security

Vaazkl for funny ‘memes’ (mostly tweets and stuff, but still great)

Homework Radio , LoFi Girl, and Chillhop Music if you want LoFi to listen to

Horror Babble does some great horror stories
