I would suggest you re-read your comment in a week or so to see if by then you are far enough away from writing it to see how others perceive it. If it wasn't your intention to be negative then maybe it is my non-native English capability that is the cause of this but even upon re-reading it that's how I perceive it.

- You start off with commenting that the author has a knack for self promotion and invention. My impression is that he's putting in a status report for a project that is underway.

- you follow this up with something that you can't possibly know and use that to put the project down, whilst at the same time positioning yourself as a higher grade authority because you are apparently able to see something that others do not, effectively doing that which you accuse the author of: self promotion.

- You then double down on this by showing that it was you who pointed out to the author that there was a bug in the software, which in the normal course of open source development is not usually enough to place yourself morally or technically above the authors.

- You then in your more or less official capacity of established critic warn others to hold off putting this project to the test until 'adults' have reviewed it.

- And then finally you suggest they do it anyway, with your permission this time (and of course now amply warned) with the implicit assumption that problems will turn up (most likely this will be the case) and that you hope 'there won't be too many false positives', strongly suggesting that there might be.

And in your comment prior to this reply you do that once again, making statements that put words in the mouth of the author.
