Alexa, show me how to drive a significant portion of your customer base towards unashamed piracy.
Significant portion of what kind of users exactly? Professionals upgrade their software and I could bet that 13 years old software is nowhere near of being significant. It’s the same kind of stupidity like shouting that Microsoft EOLed XP. ;-)
I found it to be a treadmill - the prices went up until Adobe decided that you could no longer purchase anything outright and now had to rent it. Newer versions looked prettier, but the performance and stability dropped.
I’d reckon that the vast majority of people using CC would be happy with an older version and just as productive. CC6 and later are resource hogs that are constantly calling home. Today, I’d be hard pressed to choose CC over a pirated copy or other alternative, and I’ve known a few designers that stuck with cracked copies of CS.
