But your dislike can be a lot of other things which are not objective the slightest sense. I mean, your whole article is a subjective piece. Also, stating about something that you “dislike” something as large as Spring as a whole is usually a huge red flag for anybody, just like how liking it without reservations is also a huge red flag.
From my point of view, it seemed from you article that you didn't even really understand functional languages in two decades (at least Haskell), which it seemed you to try to state also. So that doesn't matter too much.
Anyway, I just wanted to say, that it's totally pointless to state something like "I know it well"... Say what's your problem with it, "I don't like it" doesn't add anything to the conversation. I'm quite sure whatever you would say as problems, most people would agree, maybe there would be even tips under it how to prevent it. That will never happen with the kind of comments which you made above.
Yes, of course it’s (largely) subjective. But I have actually read much of the source code of Spring. I know it _very_ well.
