Between iTunes and Bandcamp, it's very easy to buy DRM free music (most of the time). In the streaming era, its basically impossible to buy TV shows and movies without DRM.
…and, if I may add, shops like https://www.qobuz.com/us-en/shop , which fill the gap of providing HQ downloads of popular music that cannot be found on Bandcamp. I have to admit I haven't used them in years (ever since I got a Spotify account) but they used to be my go-to place for purchasing FLACs.
