It’s worth noting that instances like this will be limited as the frankly frightening figures only apply to people who’ve stacked subscriptions several years into the future, but the backlash will be enormous if this also occurs in the United States and Europe. Those who stack subscriptions are, after all, likely to be the most dedicated, loyal, and vocal customers.
Not really defending them on this, but...did Sony ever
technically, outright state they were supporting stacking? I remember them saying they would convert any active PSNow subs to PS+ Deluxe/Premium for the duration remaining on the Now sub, and I think that applied if even only just had now, not PS+ & PS Now. Additionally, they said something else WRT those with PS+ and PS Now but I can't recall what it was.
That said I don't think they ever said anything validating people who were trying to buy PS+ subs for like a decade to stack them for a higher tier of PS+ Extra or Premium; not only does that sound like an obviously stupid loophole, it kind of also defeats the purpose of what it seems like they're trying to do here i.e grow service revenue. If these service revamps are going to mainly apply to core/dedicated users anyway (at least to start with), and they have a propensity to try taking advantage of things like extreme stacking, that probably creates a net stagnation or negative for what the company wants in terms of revenue growth.
Yes I know as a gamer it probably sucks you can't stack PS+ & PS Now to 2040 and save like 90% off the normal sub rate but, were you ever actually legally told that was going to be an option with what they allowed beforehand? Again I'm just going off the info I remember, but I do remember a lot of people rushing to try buy PS Now cards to "take advantage" of the revamp. I considered it, but ultimately rejected it because for 1, I don't think $90/year or $120/year is a bad deal for what's being offered in my specific use-case, and 2, I knew it would result in some messy BS like how things always get messy when you try gaming the system.
Also to the bolded, I actually think that's somewhat false. You'd think the "most dedicated, loyal, and vocal customers" would be willing to pay the normal rate if the pricing was fair. It's like saying someone who waits for all your big AAA releases to hit clearance prices or steep discount sales before buying is a "most dedicated, loyal, and vocal customer". Well, they're probably vocal. "Dedicated and loyal"? Well in terms of being a revenue driver for the ecosystem, definitely not
