No, if anything the way you can tell you are in a dream is because the top spins forever and never starts wobbling; the way he got his wife to eventually concede that she was in a dream was by setting the top in a perpetual spin so that she stumbled upon it still spinning.
The significance of the ending is not that he is still in a dream but that he is so content with the situation that he stops caring whether he is in a dream or not. (Actually, in fairness that is not quite true either; I've heard that basically the ending is more Nolan trolling the audience than anything of narrative significance.)
Alternatively, instead of reading a Phoronix article that has a couple of short snippets from a much longer blog post, you can read the original blog post yourself to see the full context.
Edit: Also, it is worth noting that the author of the original blog post had previously written another relatively recent post criticizing the way in which Wayland was developed, so it's not like they are refusing to see its problems.
