The post on… the opensource Lemmy community for self hosters. Is that the one you’re talking about?

The marketing claims it’s “a gift for your family”.

Not a single comment in that first link mentions family members using it.

Here are the comments from the “people listing their use cases” you mentioned:

• wow, this looks awesome!
• it might be nice to have the a local storage option
• I really wish it has a linux native app and an android app, hopefully in f-droid
• As the admin of the !journaling@sh.itjust.works community

My issue isn’t the app itself or it’s users.

It’s the claim that it’s “a gift for your family”.

So this Thanksgiving, give your family the gift of memories that last forever!

What is this marketing?

I cannot imagine a single person who would want this for Thanksgiving.

Most people under the age of 30 use social media now to “preserve memories”.

The people who care about journaling probably have physical paper journals and wouldn’t want an app.

And the people who would want an app… would probably already have installed this themselves.
