I didn't realize that! Though in researching it, I found that the law allowing resell is somewhat linked to the original install media, i.e., you couldn't sell the license key and a backup copy. I don't see any EU cases that square this with digital distribution, but maybe this current ruling will provide guidance on that issue.
This basically added jurisprudence that digital downloads can be resold provided that the original is made unusable.
Most software EULA say they are non-transferable, but that court order overrules it. That restriction has become meaningless. Interesting!
That case was one of the reasons that Adobe and Microsoft switched to a subscription-based model for their software suites.
That makes sense. I also saw some speculation that it's helped accelerate some vendors' efforts to convert customers to cloud offerings. On the other hand, I saw a very insightful analysis that thought vendors fighting this were being short sighted because annual maintenance can often be upwards of 20% of the initial license, and so recipients of second hand software would still be more than making up for the revenue in the not-so-long term.
