Proprietary is a strong word IMO. Here’s the repo, it’s not FOSS, but it is source available.
Yeah, that’s what I meant by “proprietary”. I guess having the source to look at is better than nothing, but it still leaves me uneasy. Their license lets them do anything they want (ignoring that - as it stands - their license is void due to the linkage with GPLv3 code, but they said they want to fix that). I have no idea what their plan is. I don’t think it is in their best interest to go the route they appear to be going. Having truly open source clients seems to be a selling point for quite a few customers. But what do I know…
I don’t see why this should make any difference at all. Sure, I get why he is are saying they are going to fix it - he thinks that this gets them in compliance with the GPLv3. But from a practical point of view there is no difference at all. The software is useless without that SDK part. Even if it does indeed get them in the clear from a legal point of view (which I am not convinced that it actually does), it is still a crappy situation.
I think, it would look way less shady, if they said they are going fully source-available and not pretend that they are keeping the client open source. I would still dislike that, of course. At least that wouldn’t have eroded the trust in them as much as it did for me.
