Everyone is renting software. That being said, you either value Office at 70$ a year or not.
Yes, according to most software licenses we "rent" the product, but there is a difference between this traditional "buying" of software and the subscription-based model:
If I purchase a license of a program, it's a one-time expense that I make when I have the funds, and I know I'll be able to use it for as long as I have a computer that runs it. There may be an update price later on, but that will still be optional. If I don't upgrade, I can still use my old program. It's not a recurring expense.
If I subscribe to a program, I pay a monthly or yearly fee, which typically leads to a substantially higher price over the course of several years, and I will lose access to the software the moment I stop the regular payments, regardless of how much I already paid in the past. That is a business model that I won't support.
Throwing around words like 'I will never have a subscription' is really just masking that you don't think Office and unlimited storage is worth 70$ a year.
I don't buy eggs from places where chicken are kept in small cages. I do this because I don't want to support a practice I disagree with. It doesn't mean I am "masking" anything, but indicates that I'm aware that money talks.
It's the same with companies that switch to software subscriptions: I disagree with the practice and will not support it with money, because that's the only "vote" I have. Whether the program is worth the price is completely irrelevant to that decision. I'd rather settle for a lesser featured program that I can purchase properly.
Just like I pay more for my eggs.
