TL;DR:
"Would [...], if [...]" is the meaning of "could". Seriously...
"Some people doing something properly is better than a bunch of people spamming out worthless AI garbage." or "Some people doing something properly with AI is better than a bunch of people spamming out worthless AI garbage." Now, either is an objective statement I can agree with.
If you were a developer, you'd know that using a single prompt — which would be having it done for you — does not get you anything worthwhile. Using it as the tool it is, however, is assistance.
And no, you're not Owner of Humanity and Decider of Fates, Acobham, the Knower-Whats-Best. You have no prerogative to restrict or in any way judge others' use of AI when you have no vested interests in the result, other than to express a personal opinion. "Never look a gift horse in the mouth."

What? For all you know, the dev might be a senior developer who spent an hour after work over the last months making this as a part time, passion project, precisely because he knew he could use AI to save him a lot of boilerplate and setup work.
He likely would NOT have done so if it had taken up all his time.
A game would not exist without AI just because a dev knows how to code. Just how knowing how to write doesn't mean you have time to write your own memoirs.
Not everyone has the time to spare to dedicate to all the projects they want to see completed.
I could almost agree with your second statement. It would have been perfectly reasonable, had you not felt the need to specify "AI" solely one the side that is perceived as negative.
Some people doing something properly [whether that be with or without AI] is better than a bunch of people spamming out worthless AI [or handcrafted] garbage. As it stands, that does not constitute a point against AI, but rather an opinion. You made my point for me in that. Creating half-finished products that don't have the most basic features because the devs had no time to add those doesn't automatically make them "good because handcrafted". Bad games have been spammed out for decades without AI.
And you're clearly not a developer, nor are you well-versed on AI in development. It's bad at anything other than auto-completing boilerplate code, auto-completing settings for tools and other systems and setting up presets, and auto-completing inline; that's all it can do. And for those, there were tools that handled it before AI; now they use AI. Nothing has changed, other than people hearing AI and going nuts. Anything AI does now, tools did before. Only, those tools required complex setup and handling, so they got replaced.
Assuming that a dev doesn't know how to program just because they use AI is nonsensical. As explained earlier, it's a useful tool for dozens of mind-numbingly repetitive tasks. Using a single prompt for AI to create a game for you is simple and results in trash. Using AI in development is little more than auto-complete for longer sections; you still need to have the required knowledge, or you'll end up with an unmaintainable mess very quickly.
And even then, being made purely by AI is still not a quality factor, just an indicator.
And lastly: No. Something being free changes everything. You are not entitled to demand anything you see being made according to your opinion. If you paid for it and it turns out that they put in less effort than you thought would have been worth the price at the time of purchase, that's a just complaint. Getting something for free removes that relationship between the price you paid and the (perceived) worth you received in return and renders your demands void.
