The license doesn't comply with the Open Source Definition btw. https://opensource.org/osd/
Yes. Nice product and fair license. But do not call it open source. Flagging the post for false advertising, will unflag if they fix the page.
People disagree on this, but flamewars are just unhelpful at this point.
The source is open in as much as it’s available to read and actually do what you want with (self host etc)… you just can’t use the code to sell the same product yourself.
As a builder myself I think this is perfectly reasonable, and arguing the toss over whether this is “pure” open source is pointless imo.
For me, it is open source (it’s open, look at it, use it!) but it just happens to have a license you don’t like/agree with.
