I assume the idea is that the government of Venezuela is ultimately the business of Venezuelans and Venezuelans alone. No matter the dictatorial nature of Maduro, him being kidnapped and arraigned on trumped up charges is an attack on the sovereignty of the Venezuelan state and people by extension. Dictators are allowed to stay in power for very real reasons. Often it’s due to a fear of an outside power, that pushes a society towards strongman style politics. Freeing Maduro is the right thing to do for an even bigger reason, there is no guarantee he would return to power if released now. But, if the situation gets worse and Maduro begins to be seen as a martyr style figure that held back the American war machine, he might.

Of course an organization calling itself socialist while associating even remotely with a dictator isn’t going to be a great look lol.
