DAU and MAU are tricky metrics partly because even when they're known to be problematic (perhaps the definition of "active" is too permissive to be useful for certain purposes) they are very hard to change because they are reported at such a high level (frequently without relevant context such as whether or not they are counting accounts or users) so historical changes are trickier to get support for. Also people want that number to be defined to yield the highest number because Goodhart's Law and we ship what we're incentivised to ship.
