I have not seen the mention of base unreal engine outside of Twitter, but the change for UEFN has been noted elsewhere:

Its hard lol. I rarely take pride on positives and mostly dwell on the negatives. Not good or healthy but what are you going to do.

Flaws are hard. I’ve gotten some pretty brutal review smackdowns for things that were largely out of my control, or things I was aware of but couldn’t fix in a satisfying way, and that just feels awful.

But on the flip side I got reviews that pointed out issues I had never seen or even noticed, or worded it in a way that clarified the issue, and those are helpful.

All you can really do is remember the dev is human at the end of the day. Full of flaws and likely jumped on a project too ambitious for their own good.

They only have 7 days to fix the licensing or their licenses are revoked? Is Unity that hard up for cash?
