I don't believe I'm straw manning, and I think your characterization of that is a little unwarranted.

There is no study that conclusively points to it being harmful, that is true. But when there's a lot of money on the line and conflicts of interest start getting involved, I don't think it's entirely out of the question to be at least slightly wary of the 'official' recommendation from a verifiably financially biased institution. Regular folk aren't going to research all 154 studies on a single sweetener, making them inherently reliant on institutions (who can do meta studies) for advice. It's the quintessential laymen's quandary.

The EU seems to be, at least nowadays, a more trustworthy source regarding food safety, and are certainly more willing to reverse previously incorrect assumptions, such as when they reversed the ban on Cyclamate sweetener when it was found to be safe (yet it remains banned in the US). They, so far, also deem aspartame safe, and it's difficult to see how exactly it could be dangerous.

Is it safer than sugar, where there are known dangers? I think so, I'd pick a diet soda over a sugar-based one any day. But I think it's healthy to at least attempt to ensure the answer recommended to us is as unbiased as possible.

By the way, the article itself doesn't even suggest that aspertame is that dangerous:

“My big concern is that I don’t want people saying, ‘Oh my gosh, I’ve got to stop diet sodas, I’m gonna get sugared sodas,’ and then they start drinking those and gain weight, which we know is one of the major cancer risks,” said Bevers. “And that has solid data.” A better outcome of the recommendation would be if people who drink a ton of diet soda replaced some of it with water.

I think the takeaway from this article should be "Aspartame is probably pretty safe, but holy shit one of the main institutions we have in charge of determining that, along with a bunch of other substances, is basically corporate captured, so get your advice elsewhere."
