He doesn't provide the context for what his timescale is for his specific case. He cites that it can be up to 30 days later and Honey will still take the commission, which is true, but most merchants don't honor any cookies that are older than a day anyways.
I'm not saying this isn't a problem, it's just not a Honey-specific problem. If he actually wanted to influence change, he should cover the affiliate networks responsible for dictating this behavior (CJ, Impact, Rakuten, Awin, etc). The extensions are forced to comply by their rules.
