To play along, activation is still a potential issue. Affinity v1 suite had offline activation so one can always activate on any new system/install, while v2 (for its non-volume license at least), which since brought along an optional subscription model, switched to online activation.

Looking at Adobe multiple versions have phased out online activation support over the years, with a not uncommon complaint being trouble installing and using purchases subsequently. As with anything tied to server checks one has to trust it will either continue working or workarounds be provided.

IIRC Clip Studio Paint switched their activation method in the last few years as well.
