This is a common problem across militaries. It is difficult to stop soldiers from leaking their location if they have access to mobile phones and the Internet. Individual cases are usually a combination of naïveté, ignorance, and an unwillingness to be inconvenienced.
It still happens in Ukraine, where immediate risk to life and limb is much more severe than this case.
About 15 years ago, our brigade conducted a training exercise to test overall readiness. The opposing force (OPFOR) figured out how to triangulate the brigade headquarters' position using Tinder.
Tinder provided 1-mile granularity, so OPFOR would roam around until they had enough points to locate the headquarters. Then, they'd artillery it out of existence. The brigade commander was most displeased—moving a brigade headquarters is not for the weak or fainthearted.
I agree with Ukraine, but only when it comes to the first two or so years of the war, by now most of those that didn’t respect those rules (I’m talking both sides) are either dead or missing some limbs. With that told, just recently the Russian MOD has started applying heavy penalties to its soldiers close to the frontlines who were still using Telegram and/or the Ukrainian mobile network (?!), so it looks like there are still some behaviors left to correct.
It's this kind of incident that gives me faith that the military isn't hiding aliens and in fact pretty much any grand conspiracy that requires secrecy across a large group of people for long periods of time can pretty much be dismissed immediately.
One of my favorite examples are the soldiers who leaked classified information to win arguments on online forums [1]. Similar incidents have occurred with a Minecraft Discord [2].

There was fitness tracker that posted locations without user names.
Well, wouldn't you know, in Iraq there were all these square paths on the map. Yes, it was Americans jogging just inside the perimeter of small bases.
Just like with the aircraft carrier, these bases were not secret but it shows how locations can leak unexpectedly.
