Open source Adobe alternatives
nicely categorised options if you don't want a subscription
The amusingly named ASS (Adobe Sucks Scrotum) microsite lists Free, Free and Open Source and one time payment alternatives to Adobe.
I can see why Adobe moved to a subscription model (it makes complete business sense from a recurring revenue perspective) but for those that only use certain products very occasionally and don't need most of the featureset, it can be painful paying every month.
I'm a big fan of Affinity Designer and Pixelmator Pro for their rich feature sets, native mac performance and buy-once pricing.
