In reading the title of the post in question, as well as this comment, I'm going on a bit of a brief tangent:

Why can't we all just get along?

I think it's great for someone to say:

    "Hey guys, I find it fits in my workflow really well to not use SDK's, and I
    feel I get a lot of benefit from it."

I think we'd all agree that a similarly toned response would be great:

    Interesting approach, thanks for sharing why you do things that way. If I
    may chime in as someone who designs these SDK's, we really target them
    towards people who have less experience, and who need simpler tools to get
    things done. We'd counsel everyone to keep this in mind when picking tools
    to use for their projects. Remember, always be thorough in exploring your
    options and choose the best tool for the job!

See how nice that could have been, for both parties? I don't think we benefit from titles that come across as vaguely hostile like "Why I Don't Want Your SDK in Production", or from responses that might be interpreted as overly dismissive like "That's cool. You're not the guy we built it for".

I am conscious that this post might come across as condescending or insulting, but I'm genuinely not trying to go for that. I like hearing the different opinions people have, and it bothers me that there's such low level hostility and tension in much of the discussion I see. I hope we can all be a little nicer when we talk online.

Seriously, we can all get along!
