The devs seem to have made a few enemies. Devs of other small projects, specifically Nim and Zig aren't fans of V to say the least. Nim devs allege that the V project has made defamatory remarks about their project. Zig developer, Andrew Kelly, also had some things to say about V. [0],[1]
There have been numerous occasions of the V dev deleting criticism.
There are claims that the V project has been buying stars on github.
The project makes very bold claims about the feature set while not having actually implemented said features.
There is a popular set of blog posts that dives into the issues with claims vs reality [2],[3],[4]
My opinion is that I do find it disingenuous, and borderline scammy, to accept donations and at the same time claim V can do the things it claims. Ultimately, I think the dev is just not great at managing expectations. I highly doubt any of it is malicious intent. Also, somewhere in one of these, Andrew retracts his accusation of fraud, due to the V devs updating the advertised capabilities of the project.
