Vote with your money. Don't buy Apple or Google devices, don't pay for Netflix or similar DRM streaming systems, don't buy Kindle books, don't buy Steam games. Buy unlocked media only, and don't forget to create some of your own.
I wouldn't ever buy content I will own with DRM, but if you think you'll ever see streaming without DRM you're crazy. Personally I've done my fair share of pirating for various reasons, and I think streaming services are the ONLY reasonable use case for DRM. You aren't actually purchasing content.
