People who wish to mask their crimes have a greater incentive to use E2EE so will probably gravitate towards platforms that offer it. I would therefore suggest those not committing crimes are disproportionately affected by E2EE not being made the default where possible. Once one service in a particular category offers E2EE, the benefits of the other services in that category not offering it is significantly reduced.

This is only true if you assume that the world is populated with an equal number of criminals and non-criminals.
