That's probably because it is hard to object to or agree with an idea so vaguely formulated. Yes, objects in some sense could be and have been treated as relations, and vice versa, so what ? Some commercial SQL databases even have both implementations, 'objects as relations' and 'objects as attributes'. Until and unless you define some sort of object algebra and compare its features with the relational algebra or some other algebra of relations, there is nothing to argue about !
