Proof that Adobe is making a killing on people who can't do math. It's like people who borrow at "reasonable" interest rates and think they're not losing money.
The purchased apps are only more expensive if you upgrade every time a new version is available which many, many people simply do not do and do not need to do. In fact, every business I've ever seen prefers stability in their toolset over jumping on each upgrade. My current employer was still using CS2 before they were forced this year into monthly payments. The subscription method forces you to continue paying whether you use the latest versions or not. The math is grade school level simple. In the long-run, you're paying significantly more in the subscription model than purchasing outright.
And yes, the latest versions of Adobe's software blows chunks. Just yesterday, I had to restart my Mac because Adobe's background desktop service was eating up significant amounts of my CPU time and had caused my Mac to slow to a crawl. And I'm not the only one seeing this:

Never had this nonsense with earlier versions of Adobe's apps.
