Based on your recent posts, I will give you the benefit of the doubt of being extremely naïve. But similar to pointing out to you that a "cheap professional" and a "standard accountant" aren't anything real, so too (yet to a greater and harsher degree) I will point out to you that anyone who wrote what you purport to have seen in a sefer, is a godol of similar stature to the gdolim present in 770's מרכז גוטניק לקטנים ולגדולים!
I know that some idiots have falsely made such claims in the past, but putting something like that in print takes it to a new level.
Remember, this purported "opposition" based on not sleeping in the Sukkah is nothing more than:

I don't think I can answer this post, as I currently only have 5 or 6 bags of popcorn in my house.
I was not trying to stick my head into the reasons Chabad has been opposed by a number of litvish gedolim, nor am I qualified to take sides. But the fact nevertheless stands that this is clearly the conception of some BIG litvish gedolim. Again, I'm not trying to say who is right, but I know of at least one such sefer that includes a letter from well-recognized gadol (outside of Chabad) that tells a school not to learn seforim from the Lubabvitcher Rebbe because he "removed a mitzva from the Torah" by ruling not to sleep in a sukkah.
Again, I am not saying anything about the factual correctness of it. I'm only saying that such a sefer exists. You can rebut the claim, and I look forward to reading all your future posts, but please don't make this into a personal argument with me. I don't know much about this, and I have no interest in getting involved.
About cheap professionals, I know of
at least one. And about standard accountants, the question I had was how much a standard accountant charges, in which context, 'standard' does not mean a non-professional, rather a typically-priced accountant.
