My layperson's armchair guess is that a successful attacker would probably seek to keep it quiet.
If you were a bad person, and you got access of tons of credentials from one of the major trust-us password managers, would you:
1. Focus on finding and looting big-payout cryptocurrency stashes, as quietly as you can (so you can keep doing it longer, before news gets out of how)?
2. Sell to a state actor to use for probably high-value purposes, while keeping it quiet?
3. Something else, and would that involve keeping it quiet, or making a big noisy mess?
1. State actors
2. For profit criminals
3. Teens for lulz and street cred
I guess the first group would probably keep it pretty quiet. The second would keep it quiet until they've abused the data as much as they want to, then sell the remainder on the dark web. The third would make a big noisy mess right away.
2. Inject code in build to export user's passwords to remote server after update is installed
An offline password manager is updated a few times a year, and will go through OS repository distribution, with verification of the signature for changes. Or you can download the software from the source website and check the signature.
Now that's not to say that something can't be sneaked into other work! But the bar is a bit higher than "take over a dependency"

Several years ago the trendy thing to do for security was to get a USB-A security dongle and lock your important accounts with it. Nowadays, laptops from several major manufacturers no longer ship with a USB-A port, so if you need to log in again and don't have a USB-C dock handy, you're locked out until you can find one.
Either way, availability can be compromised by a hack due to passwords being phished and I think I'd prefer dealing with hardware tokens than the fallout of being phished or otherwise suffering credential compromise. That said at this point I probably wouldn't issue hardware tokens en masse until proper processes are in place to manage them (and their loss/breakage/etc) - it's certainly not solved to my satisfaction yet.
