Let me start with the obvious. Constructive feedback is the only way forward.
I've been silently reading most of the threads in here (most of the times I have nothing to add, hence the silence) and I agree with you 99,99999% of the times. But. I guess since you started this topic, you are open to criticism as well.
I have to concur with the majority. There's a problem with your tone. Whenever I read one of your replies, on top of your replies (just to visualize things, I'm a designer, I can't help it) I see a watermark reading "You suck, your product sucks, your method sucks, go home, next!"
For example, in this thread your #1 questions is:
"your plugin is awesome according to whom?"
It's awesome, according to him, what's your problem anyway? It's his baby. Do you know how much time he's put into it? No. So you're completely off-topic right off the bat. You don't know the author personally but you do make it personal. Why? Is the fact that someone called their plugin awesome an indicator of looking for butt kissing feedback?
Again, I don't have a problem with that. Someone else? meh... possibly. People seek advice on their products/services in here, not on how to man up.
And again, you don't know who you are dealing with. Just provide your feedback and move on. Everything else is noise. Noise that you create and have no idea about the impact it might have to the post author.
Let me tell you a little story. I started my WordPress themes business almost 5 years go so I can pay a (mid) six-figure debt. 50,000 paid users later, everything's back to normal. Debt paid. Sorry, no drama here. In order to achieve that, especially in the early days, I would email almost every customer asking for feedback in order to improve our themes. It really worked. Most of them would ask for improvements here and there while others expressed their concerns about the whole operation altogether. One of them actually told me that "I wouldn't last very long". Did I give a rat's hat about comments like this? No. Why? Because I didn't have the time to deal with random stuff like this. If I had to deal with this kind of feedback 20 years ago though, well, I'm sure I would have just given up. End of little story.
All I'm saying is next time you press the reply button, have in mind that you don't know who you are talking to. Stick to the facts and just provide your valuable feedback. I'm saying valuable because, from what I read, you are a professional paying serious money for your tools.
I hope you are not like this right now https://giphy.com/gifs/angry-the-office-screaming-3t7RAFhu75Wwg because as I said, I agree with you most of the times. Just do not create unnecessary noise
