There is more to this argument. Adobe made themselves an industry standard with a perpetual license - pay once, own forever. Once they transitioned to a subscription model with a strict cancellation policy, it became the only option.

Saying that designers could have just continued using Photoshop CS on a 2006 MacBook doesn't reflect the reality of hardware updates and the changes in the industry-wide design trends.

Which, I would argue, is why perpetual licenses are not all fun and games... They didn't revoke any of those licenses

The concern is here is clearly not the revocation of licenses.

The cost of not just learning but becoming a professional user of a specific set of tools is very high. Then later as time goes by being forced to either abandon these tools or to accept a different pricing model is - to many people - unfair and unethical.
