When the audience for your game is rebelling and you are losing DnDBeyond subscriptions at a very high rate, and you are doing things to turn it around, you're making promises. If they said "we'll release it to CC" and still hadn't done the 5e SRD now a year+ later, we'd feel they broke their promise, not just that it "slipped in date a bit".
I feel this part feels like a small, unimportant add-on to you, so for you the impact is minimized. But this with all of the full d20 games that were published, on top of the 3pp supplements, this is actually a bigger deal than the 5e SRD being put in by one measure.
So here's my response to you in the form of a choose your own adventure.
If they hadn't yet put the 5e SRD into CC yet...
...and Dire Bare thought it was a broken promise, then it can be the same to others for 3.x SRDs.
...and Dire Bare thought it was just a slipped deadline, then they would find themselves out of sync with the majority of players who would be still calling for WotC's virtual head.
