Strong disagree. I've been on the receiving side of many such requests and all of them came with reasons and citations to back up the request. I've never had a single LE request (including some from the FBI even though we were located in Toronto, Canada and in IJmuiden, NL meaning that we could have refused them simply on account of not being in their jurisdiction) that did not make perfect sense to me.
2. Whether you agree with the LE request has no influence on whether it's legal or not.
The context was quite comparable: live conversations, messages both public and private.

Twitter had an extensive legal team before Musk fired them all, I'm pretty sure they were well capable of determining which requests were legal and which were not.
