I think the issue there is that, in the absence of the AI poster, people will still dislike the "worse" poster.
Since this is idealogical, a business owner's choices are: * use AI and some people hate it on principle, don't use AI and don't pay enough and some people hate it because it looks cheap, don't use Ai and pay a bunch more and people don't hate it...maybe, depending on style and skill of the artist.
As a business owner, it's not an encouraging situation.
Do people really care much about how beautiful a human made poster look like? I don’t think I’ve ever seen that as an issue, a poster doesn’t have to look fancy. Though if I love any art piece then learn later it was made by AI I will for sure update my judgement and dismiss it as if I was tricked in the first place. You’re way better using Word art for your poster than delegating to an AI if you don’t want to receive negative attention
None of the AI haters (or haters in general) are willing to put money where their mouths are. None of them are willing to pay for better human artwork, yet have the audacity to criticize as if top artists owe them free output.
An AI generated poster signals low effort. If you're too lazy or too cheap to make a real poster it makes me wonder what other corners have been cut.
