"
If you cannot install the software you want on your own device – you don’t own it."
For example If I could install KOReader on a Kindle without jailbreak it (a complicated and risky procedure, and not always available) I would buy a Scribe. So I won't buy it.
Let's also not forget the possibility of extending the life of our devices.
Obviously I have no hope that the initiative will be successful.
