We've been an all-Affinity shop for a couple of years now, with zero regrets. Like many people, I had reservations about Canva acquiring Affinity last year, but so far, I haven't seen anything to complain about. V3 is exactly what I was hoping it would be, and the fact that it's free is just a bonus. For everyone asking how and why it would be made free, it's simple. This is a long game strategy for Canva; clearly, they want people to pay for Canva Pro, at $15 a month, but there's more to it than that.
1) Canva is built for marketers, not graphic designers. Affinity is built for designers, not marketers. The tools complement each other, and once they have two-way integration, it will remove some friction points. I know that 90% of the client files I receive daily are created in Canva. If I can just pull those into Affinity in the future and then make them press-ready, that's a win for me.
2) The current generation of marketers, as well as future generations of marketers, are cutting their teeth on Canva. If they ever want to level up, they can now stay in the Canva ecosystem instead of moving to Adobe. That's a win for Canva. It's no different than Apple giving away Emacs to schools 25 years ago; they were planting seeds that are now paying off in spades. Lifelong Canva customers.
3) It's a very similar approach to what Black Magic has done with DaVinci Resolve, and no one can deny that DaVinci Resolve has absolutely dominated Adobe in the video editing space over the last decade.
Canva has VERY publicly stated that they aren't training AI on Affinity user data, but why people keep saying that is beyond me. Anyway, we will continue to use Affinity happily and hope to for many years to come.
