I never said one should be fighting. My point is that POs/PMs should know the domain at least as much about the domain as TLs do.

The problem is not needing discovery work or understanding the problem. The problem is when the Tech Lead is the one who's providing all the data for that discovery, or helping them understand the problem better, because of lack of expertise of PO/PM. Or having to push back because of incomplete knowledge.

If there is lack of information or incorrect information, POs should be able to get that information themselves. If a TL is the sole source of that info, then it becomes an issue.

IME this is very common. And it takes too much time of a Tech Lead's day.
