Not who you were replying to, but yes, it's a special case. For anything not having to do with a formal math-like proof, you want "has proven" instead of "has proved." It's super weird.
We only have a few of these in English, where one of the tenses of the verb changes depending on the subject matter, but they do exist. The only other one I can think of off the top of my head is hang: past and participle "hanged"/"have hanged" (to execute or be executed via hanging from the neck) versus "hung"/"have hung" (any other meaning).
Hope that helps!
Edit: fixed my example to better match the original text.
> Basically, what you mentioned—' I don't want to pay a full price' and 'try the full functionality out without paying the full price'—are the primary drivers behind customers' preference for a subscription-based model.
Or a third driver, somewhat related to the first two: the customer is simply priced out of the product in question as a one-time payment.
Part of the reason Adobe makes the killing it does off CC is because it's $55/mo and not $500-$600 or whatever. It doesn't require a consumer to have a chunk of money in their bank account all at once just sitting around, which especially in the case of students and art folks is money they may not have.
That's fair. I wasn't coming for you and I'm certainly not trying to fight you from some kind of authority - I'm definitely not a businessperson.
The only point I was trying to get across is that even "bad" customers are still customers, and that there's still a lot of money to be made meeting people's needs doing the work others don't want to do. I feel like this applies from the bottom of the socioeconomic ladder all the way to the top - that's all. Perhaps I should've made that clearer, and that's on me.
An unsolicited side note: I think the bristling to this post was because of the language you were using. Talking about the poor as if they were to be discarded made you look a bit as if you have no empathy, which might not be fair to you. I get it - business require being hard-hearted if you want to get ahead because if you don't make tough decisions, someone else will - but it probably wasn't your best look, you know?
There is an argument to be made that price-sensitive customers are a neglected market. Granted, marketing to them is very different - they're prone to being scooped if someone comes by willing to sell your same product to them at a loss (hi, Amazon and Walmart) - but there are a lot more of them and you're not fighting every startup on the planet for the same handful of clients.
Business have made a killing in China and India for a reason, after all.
