Shorter licences and conditions
Licences as done now, even for free stuff, apparently have to start from scratch every time. Whereas ideally if you have already read "GPL v3" or "Microsoft EULA" then you know what the terms are. If it's exactly the same thing again - and generally it can be - then you shouldn't have to read it every time.
Broadly a licence usually does some of the following things:
- Grants you some right to use the software until told otherwise, in limited ways, for a price
- Declares that the software author is not to be held unreasonably responsible for bad outcomes
Maybe it would be useful for a third party service to let you create an identity and certify that you have already read the licences. Of course that isn't the same thing as -accepting- the licence for every product.
But while licences can be made more straightforward if everyone acts in good faith, some people don't. Software may be published that is downright malicious, and if the publisher is particularly vindictive then they may make you "read" a licence and "agree" to receive spam or even to send it. And of course some users want to use Microsoft Windows to view media that WASN'T created using a legally licensed copy of the relevant codec, or want to remote-access applications running on Windows Home Basic which is another licence violation, or to reveal performance benchmarks without getting Microsoft's permission first. But those people probably don't take time to read the long scary licences that we get now, so it doesn't make a huge difference.
