You bought Borland C++ compiler, installed it and used it - you were free to buy the next version when it came out or not.
However think on your own salary and how many copies you need to sell, at what price, per month, to receive the same monetary amount after taxes.
Add to it, the amount of new user acquisitions per month, to keep a sustainable salary level.
Adobe tools are subscriptions and they get pirated all the time.
If you're trying to make people cheer for the pirates, you're succeeding.
It seems to be going very well for video and music streaming services. Piracy is certainly nearly dead at this point and not at all at record-high levels.
I'm not so sure. If they can't pay for a one-time purchase, they won't be able to afford a subscription. Subscriptions are always more expensive in the end, that's why they exist in the first place. I don't see how people not using the software while still not becoming customers is a fix to anything.
As for being able to afford them, yes it cuts people out, many of whom would pirated anyway.
Digital stores, API keys, and SaaS seem to be doing alright
Adobe Creative Suite used to require a one time eye-watering payment and very few people could afford to keep it up to date, you might skip several upgrades before buying the next one if you did at all.
CC's monthly payment makes it easy to enter. You are paying more in the long term than if you bought one version of it, but less than you'd pay if you kept your subscription up -- so somebody could make the case that it is more expensive than it used to be or less expensive than it used to be.
