We have had the same discussion, and took Working Bikes's approach to do repairs (which we have been taking in since the pandemic swamped our LBS's) or help shop users work on their own, but only for maintenance or repairs to the standard parts and not the electric components (e.g. flats repaired on the non-drive wheel only).
For us this is now also partly complicated by our insurance having added a question about Ebikes (which we have answered no to) so will be having a conversation with our agent, especially since we took a donation of a like-new Ebike before our insurance renewal!
This seems like a great topic for a Discord thread or an article on the wiki: Ebikes are not a fad, it seems.
