I've read it several times over the years.
The writers said they made the Odyssey a Galaxy class ship to drove the point home how dangerous the Dominion is, it was supposed to show the audience that even the best type of ship could be taken out like it was nothing, they said if starfleet had sent the Enterprise the result would have been the same.
Somehow this hypothetical in universe scenario turned into "They planned to blow up the Enterprise and kill the entire main cast" in someone's head and others started believing it although it was very obviously not an idea anyone even considered for a second.
