Regarding the paid plan - we didn’t come to acceptable terms with the sales team - we’re a nonprofit and the offer exceeded our total operating budget by an order of magnitude (we’re a small student-organized nonprofit with many semi-active users that mostly lurk on the chat). We’d need an easy and affordable way to purchase 60k+ Push Notifications per month.
We’d also be able to live on the free version with some more admin configurability of push notifications (e.g. disabling it for certain channels or certain users), but alas there has been close to no development on this front since the limit has been implemented.
As for the other points - well understood. We’re going to make sure to change the logo. The MIT license seems permissive enough.
