I just would like to add that I strongly disagree with this post.
The HN type of users are exactly the ones which would be using something like Obsidian instead of Roam because it lets me choose how I want to sync my files and uses an easy and future proof plain text format.
Yes they might be a very demanding group of users but they are also early adopters and usually quite tech savy which has it’s own benefits.
And at least, I don’t have a problem paying for a license if I have the feeling that the software respects me as a user.
In addition just because the code is open doesn’t mean they have to let anyone contribute if they don’t want to.
And they can still have a normal support contact for their customers.
A lot of people seem to confuse open source/ free software with gratis which absolutely doesn’t have to be the case.
