I’ve never quite understood the amount of rancor that changes like this elicit here. It seems like people come out of the woodworks acting like they have been personally affronted by this, or that this is somehow directly affecting their lives. Is everybody here (planning on?) using this software to build companies with more than $25 million in revenue… and they can’t use something else with a more permissible licens…
It's a problem for people who use Akka already, not those who won't adopt it. The choices are to rewrite the service, pay a massive licensing cost ($2k _per core_!), or live with 3-year old releases with no security updates. It's very disruptive.
Akka devs are 100% within their rights to set the terms of use for their product and thus their work. There was no bait and switch here. This is just how licensing works.
