1) of course balanced critiques are necessary, but
2) sometimes you can come to a conclusion after considering all the pros and cons, and in those cases, you should definitely say so and not equivocate.
IMO that's obviously what Dijkstra did. I don't think he just had some axe to grind against `goto` for his own personal reasons. During my career I've encountered my own share of practices that I think are overused and misunderstood, and I don't need to say what they are (and thus hopefully I'll avoid a flame war), but if you've been at it for more than a few years, then I'm guessing you have some similar opinions.
I actually have nothing against "considered harmful" essays as a whole, and I often learn something from them. That said, of course you shouldn't overstate your position, which would be intellectually dishonest. For most of the problematic practices I've encountered during my career, there are some valid use cases, and it's more that they're misunderstood and misapplied that would warrant calling them out.
Anyway, I hope I've made my point.
