“Bottom line � can someone ask a shaila: a Reform person takes an artscroll siddur and copies pages with amidah � are you allowed to use it for davening?”
Did the reform Jew use the copy machine on Shabbos? If so, this would be the same shailah I mentioned earlier. Unfortunately, I don’t remember the exact psak; I think it was one of those “it’s mutar, but you still shouldn’t do it” type of things.
If he didn’t make the copy on Shabbos, then what’s the question?
“No, I mean people with left/right wing secular biases and they are comfortable with translations that caters to their biases.”
Alright. I haven’t personally met anyone like this, but I’ll take your word for it.
“even twisted translations and the like are irrelevant, no one�s hashkafa is getting affected”
Eh, if someone didn’t know better and didn’t realize the translations were twisted, it could absolutely affect their hashkafa. Again, I don’t actually think Sefaria should be wholesale banned or anything.
