I understand this part from a convention standpoint but it ultimately does not really matter (tags or content is completely arbitrary at the end of the day).
I agree with the people here that there would have been multiple sollutions to this situation, and plenty of room for coordination, that will also allow you to easily filter events that dont include a transcript.
They might have come out a bit hostile out of the gate, but understand its mostly dissapointment.
Also understand that Nostr only has 1 commons, which is not that of the servers/relays, something other protocols try and fail because its stupid. Nostr's commons is that of the immaterial (loose) coordination on standards. And we don't have a police, and technically you can do whatever you want, but commons only thrife when participants forgo immediate opportunity for the sake of long term accrued benefits.
People see you taking immediate opportunity and see the opportunity cost of that action, which explains why they are not happy.
I hope you can reflect and can come back to the table at some later moment in time.
