I mean that prior to the change, twitter gave the checkmark to famous people and brands who's identities were verified, not to accounts that they thought posted particularly good content. It was never intended to be a mark of quality in the first place. If [famous celebrity] was posting nothing but their fart schedule, they were eligible for a check. If [random grad student] was posting insightful findings from their research, they weren't eligible for a check mark because they lacked the requisite notability/fame.
