Which will just push people towards file sharing. If your DRM makes your service less convenient than copyright infringement, people will infringe copyright.
If companies start getting too draconian, the ad-blocking/circumvention/copying/sharing technologies will start getting smarter and harder to detect and circumvent. It is a battle that cannot be won.
I’d say the main obstacle in the short term is that as Google controls both client side (Chrome) for the majority and server-side can manipulate web standards to make ad-blocking harder, by exploiting their near-monopoly. They’ve already done this to an extent by modifying browser extension APIs. But people can just switch browsers. I’ve already done that on mobile. And if ChromeOS prevents it, I’ll be erasing it and installing native Linux.
You should take a look at the game Cold Waters, if you haven’t already.
