The choice is not between "content with DRM" and "content with no DRM", but "content with DRM" and "less content with no DRM".
That's only true in the short term. Those who advocate boycotting DRM infected media are concerned with the long term. If enough consumers avoid products with DRM, then the market will adapt and cease to sell works with DRM and content with no DRM will become available. That's how boycotts work.
