Historically, Google has served as the fallback for pretty poor performance from Siri on knowledge tasks, which to this day often falls back to web search results.
But, if Bing (especially circa 2016) were that search provider, it would lead to confusion all the way down. It's bad enough not to receive an answer from your first attempt, but it's much worse not to be able to receive an answer at all.
The payments were certainly a sweetener to discourage exploring (or incubating) alternatives, but I agree with the article that I don't think they could have dumped or replaced Google at that time, even without the payments.
Given a broader shift from search engines to "knowledge engines" or however they're branded these days (which, in fairness, probably drew some inspiration from Google's Knowledge Graph), I think that Apple's options are wider these days.
Taking money out of the equation (or making the offer equal between Microsoft and Google), could Bing have improved to meet the quality of Google if it had all iOS users using it and providing usage data to improve the experience? How long would that take?
I would assume the answer to the first question is yes, and the answer to the second question is too long for Apple's liking.
