Its just politics.

Susan Collins is a literal dragon, Platner has the best run on her. Keep in mind, the DNC varies in strength and organization. I think it shows Platner's campaign is willing to "play ball" in order to, however unlikely, make a good run at that senate seat. I'd say its more likely the DC consultant class that defines the national org (a class that is objectively on the back-foot, as the left is gaining nationally, albeit with mixed outcomes) thinks Platner is their best bet at an already extremely unlikely upset.

I think they have a read on him that would put him closer to Fetterman in the Senate. I think Platner is kind of dumb but upsetting Collins would be hilarious. And Platner has managed to get national attention, even pretty early on. I think he's just objectively the best odds in this race.

But I'm not to the point of even critically supporting him. I don't think he's earned a goddamn thing, being a highly problematic ex military pseudo anarchist or whatever doesnt make him qualified to lead our movements. But I think part of Platner's viability is because of a very weak bench in this race. Maine DNC clearly isn't creating or recruiting good leadership, which is a persistant problem in many political orgs.

Because he will never follow through, he's an experiment in the new move of distancing from AIPAC while normalizing and taking funds from other Zionist orgs that are less notorious

Sure they would. Look at Fetterman, Sinema, AOC...
