Oh awesome! I saw their website just describes them as “source accessible” and that github didn’t detect a license type and (wrongly) took that to mean it was an “open core but not really open source” product.

Was about to point you to MatterMost but saw it’s not open source, doh! Anyone know if it was and switched? Or was it always closed source?

Edit: Turns out it was and still is open source, I just apparently suck at researching.
