Agreed. The company I work for has fought off two "ADA trolls" in the past ~3 years. I'm fully behind accessibility, and we design/develop our website specifically to conform with best-practice; I get, and generally accept, that civil remedies are (currently) the only way to enforce any kind of compliance. I nevertheless call the lawyers targeting us trolls, because their technical analysis was beyond incompetent, and their understanding of accessibility issues woefully out of date. It cost a few days of my + developer time, and I don't know how much lawyer-time, to make them go away.

We (I'm in the US) badly need clarifying regulation. Until then, compliance will mainly be about preventing yourself from being low-hanging fruit for opportunistic litigation - which, to be clear, can generate productive results, but is clearly inefficient.
