Thanks @drawio. That's exactly why I chose a free and open platform 😠 .
@nik So we're supposed to build a complete back-end for you for free? Are you serious?

@drawio You're supposed to, at least, support some open collaboration backend.

And I cannot see where I said anything about "for free".

In any case, I cannot take your openness serious if the next thing you do is force me to go back to Google.

@nik Oh sure, we'll run a back-end that holds data and become liable for it and need to keep it running 24/7 for any issues because it's not open enough for you. Go use https://github.com/excalidraw/excalidraw.

@nik With the desktop version of @drawio you can save your files locally. This does not need any big tech cloud service.
@BaumiCoder @nik Or he could try some basic manners like "hey, are there any other way to collaborate other than using Google Drive, thanks".
