But I have found rentalware (specifically Adobe Creative Cloud as I use it) to be a somewhat positive experience. Adobe pushes out updates frequently enough where you see positive increment in productivity without it being an annoying update. Plus it has bought the price within affordable range for people like me who can afford the software if we save up enough for a few years but not the down payment in one go. Having the payment broken down over months makes it more manageable. I have been a convert from a pirate to a legitimate paying user just because of this. Straight out licenses for adobe's software cost more than some kidney operations in my country before this SaaS model.
Jetbrains has also moved onto a SaaS model. If they continue with legitimate updates every few months, then that subscription is also worth paying for.
The only subscription I do not see any benefit in, as a individual developer, is Microsoft Office 365. That's more aimed at business's whose full life depends on the software.
