How many, no, but what kind they are, as I said, certainly. We can't do much more about that than talk though and in my experience, they don't care much about what we say in here.
It certainly isn't easy to make a good browser and it's very time consuming, but if you don't distinguish yourself from the competition, you'll certainly have a problem making profits(no idea how they do that with a free browser though) since people won't be particularly drawn to it.
Currently, it still has the reputation to be yet another chrome clone(I know it's more, but that's the general opinion I see from most new user coming here). Even though it's slowly getting away from that with every version, it will take time and in the mean time, it must be pretty hard to interest people in it with a good portion of user abandoning the browser because of the changes.
I assume they know better than me how these things work and that they didn't take the decision lightly, but I don't see how they'll manage to make profits by staying a minimalistic browser when chrome already has that reputation and is much more advertised than opera could possibly be.
