Well, the clearest source is that no one claims the information was withheld, as far as I can tell that idea was just synthesized by podcasters and internet commenters. The Navy states, the WSJ reports (probably based on the Navy statement), and the Coast Guard mention that Navy intelligence reported the possible implosion almost immediately after it was discovered. The only thing that didn't happen until four days later was the release of that information to the public.

Many aspects of IUSS are still classified, and for example we can assume that the actual data will never be released because of sensitivity of the collection system. But the news that the Navy detected the implosion is nothing new, it would probably be more surprising if the Navy didn't (I don't know that the sound levels associated with a vessel of this type imploding are well known, maybe it could be explained away as the implosion having somehow produced almost no acoustic signature). We know that in the '60s the Navy detected submarine implosions (admittedly of larger submarines) further afield, and we also know that IUSS has seen major upgrades including new sensor arrays since then.

I don't use Twitter so can't confirm, but what I've heard in the news is that the OceanGate lawyer tweeted some vague, borderline conspiratorial stuff about not getting proper cooperation from the Coast Guard. I think the commentary people you refer to then boosted and expounded upon that idea.

The statements quoted here don't match the description "vague and borderline conspiratorial," but they could be misinterpreted that way, and maybe there were others.
