Yes, they paid. And they can use the code they paid for. But it doesn't give them right to leech of any future code written by someone else IN THE FUTURE.
Calling it leech isn't right, because what makes aws any different from another user? Just because they're selling the hosting, doesnt make it any different to a regular user.
Code contributions from amazon would've been leeched by other parties using redis as well - something which amazon is accepting (and probably encouraging).
And considering Redis Inc hasn't contributed the majority of the code, they won't be able to leech off other people's code because why on earth would anyone contribute to this trainwreck!
