If you don't pay the power bill, and the power company sends an email to an address you haven't used in years, they have NO duty to send out bloodhounds to track you down and warn you your power is about to be cut off.
Besides, reclaiming the expired domains *really* got Sony's attention, just as a housholder WILL notice the lights going out. It was a lot quicker and a lot less effort than bloodhounds.
The people who WORK at publishers aren't parasites. Editors, copyeditors, proofreaders, typesetters all contribute to the product.
The people who RUN the publishers are lawyers, accountants, and investors. Lawyers ask "Who can we hurt so they don't hurt us?" and the latter two ask "How you going to make money with that?" Product? Quality? Who cares?
There is NO major publisher that is run by book lovers, and it shows.
But do it with the court system. $100,000/day for each legal action they have active in the court system. Talk to a judge? $10,000/minute for every minute of delay under 24 hours delay. Their opponents pay nothing and get instant access.
I'm sure ComCrash and others will appreciate being on the receiving end of their own ideas.
