I've read the article, too. I would also bet that plenty of people who you are referring to as having a Dory-level attention-span have actually also read the article. The objections aren't because of anything Apple has said. It is what Apple hasn't said combined with known history that is the source of these objections. Commenters aren't failing to read the article, nor are they failing to understand it. They are merely connecting the dots. You, on the other hand, are taking Apple's word at face-value. Time will tell which is the more reasonable line of thinking.
While I personally don't object to subscription software (I work with many business clients and the vast majority of them prefer subscription pricing for professional software for some very good reasons that are usually out of scope in conversations like this), I do understand why people do object to it.
Yes, the current versions of FCP, Pages, etc, are not going away, and users can continue to use their current versions of those programs forever*. And we know Apple are saying that there will still be updates to those programs in the future. But we've seen this movie before with both Microsoft and Adobe. In Adobe's case, it only took one major version update to move to a 100% subscription model. In Microsoft's case, Office is still available with a perpetual license, but new major feature updates now take several years to become available to users and require a new purchase (one major feature, for example, is the XLOOKUP function in Excel. Office 365 subscribers got that feature in 2019. Perpetual licensed Excel did not receive that feature until the release of Office 2021). Microsoft has many MS Office-adjacent products and services (for example, Loop and Planner) that are subscription-only, and they've completely stopped offering perpetual licenses for some of their large enterprise systems (ie, Dynamics ERP, CRM, etc.)
Apple want to be a services company. They see the massive profits that other services companies are bringing in, and they see the successful path that those other companies took to get there. I would not say that people who object to subscription software are wrong to be concerned by this.

Asking commenters to explain why they downvoted you is lame. Don't do this.
