Well, I don't suppose the copyright owners of my software really care about it being pirated 20 years from now
Neither do I care - the financial effect of this possibility is probably close to 0 for just about everyone.
The
there always be originals argument is simply false - recently only a miracle allowed us to retrieve historic versions of CROOK and SOM operating systems for MERA computers (researchers had to crack them...). And there already are C64 games, which are probably lost forever (

And, if I understand, we are talking not only about pirated versions - but also about taking down perfectly legal free demo versions...
BTW. Fortunately, the U.S. law is U.S. law and not worldwide law (and even U.S. starts making exceptions, see
http://www.wired.co.uk/article/dmca-...bandoned-games or
https://www.digitaltrends.com/gaming...mca-exemption/ or
https://www.copyright.gov/1201/docs/...tement_01.html), so there is bigger chance important pieces of IT history will survive (including the history of cracking scene). Hopefully, software preservation projects (some of them broadly discussed on this forum) will be able to continue their work, even if they break U.S. laws. Hopefully WHDLoad team will continue their work (these pesty intellectual property thefts crack the XXth century DRMs!), and hopefully Apple won't harass you for writing software allowing to run MacOS (probably pirated in 95% of cases...) on unlicensed non-Apple hardware (which also might be a grey area).
