is it healthy for yeshiva bochurim to learn from a artscroll?
I was under the impression that he was referring to someone currently in yeshiva. Meaning, it’s not anything like 70% 30%. It’s 100% of the bochrim who are following the rules are not using Artscroll. The question is about a subset of the population, not the whole population. Obviously, Artscroll is a positive when you consider the whole population. We aren’t ignoring the lesser-educated masses out of meanness here, we’re ignoring them because they were not the subject of the question.
If you are going to phrase it that way, then the answer is I DONT KNOW and nobody knows either, Every Bocher is different. Until you know who the bocher is, you cannot answer the question. If he doesnt need it, then its a negative, but if he cannot learn without it because of his language skills then its absolutly nessasary
