It's really hard to charge money, especially against a truckload of both free AND paid tools which do the job.
They decided to NOT charge money on the number of projects or the number of runners. They've made a product with no incentive whatsoever to pay for it.
We could say it's great, we get get another free tool! but how are they going to make this work on the long term?
They have no business model and the investor funds will eventually run out at some point. Then, we'll be left with another free open source abandoned projects, just like jenkins?
