Big tech is directly influencing people today in the way so many screamed "The Russians" were influencing us in 2016 (and back during McCarthy).
I have a 500GB microSD card on my phone with all my music. I've been collecting it for decades, many from artists I meet in bars and pubs. I buy off Bandcamp when I have to, which only charges 15%, compared to Google/Amazon/Apple which charge 30%+, or streaming services that pay artists pennies.
Take control of your music. Download it, buy it DRM free, save it, back it up.
Take control of your video feed. Subscribe to YouTube channels using an RSS reader. Use 3rd party frontends like Invidious.
If you're and tech and know how to do this, than do it, and help write posts to show how others can too.
