Hi. I don't like subscriptions (HBO, Netflix, Spotify, etc.) or Apple's ecosystem. So is there a website where I can buy DRM-free movies and music like games on GOG?

For music there's Bandcamp.com

In regards to movies you're out of luck so far, I think.

In these cases, you usually put on your hook, peg-leg, tricorne hat, eyepatch and go sail the high seas.

That is as far as I know the only DRM-free option.

Yeah, add my shout for band camp. Good site that for music. Also, keep an eye on groupees.com. They often have big bundles of synth wave, metal, folk and ambient music for sale real cheap. Great value. I got the retro synth bundle this week, 30 albums/singles for £12!

For movies you are out of luck, buy on dvd and rip is your only real option.

This site is worth going through as there are a lot of classic movies available including the original Night of The Living Dead.

Many of the comedies still hold up quite well like Safety Last.

3rd on the bandcamp site for paid DRM-free music.

I don't know what you kind of music you prefer, but;
