It was not pure fault of subscription model though. ReSharper became too slow in the recent years.
I don't think they ever would have had a monopoly, even if they had kept their perpetual licensing instead of moving to subscription. The cost of those licenses was pretty high, so there was always room for someone to come in at a lower price point and undercut them.
Besides, $10/month for Photoshop and Lightroom is much more accessible than $699 for a perpetual license, especially if you don't need to use it that often.
So you pay for a year of updates, but if anyone you collaborate with updates their software, you have to as well, because you can't open the files they produce or even edit and save.
Most of the time you're paying for updates so that you can open collaborator files, not because you want new features. It's effectively a subscription paid annually.
I like to think those capabilities jumped because the new influx of Adobe refugees provided them with enough revenue to supplement their dev team. Or am I wrong?
I would argue that the more psychos in the market, the better for startups and I am quite comfortable with that idea.
It seems you lose editing access, you still can view them. Still not great, but I wanted to clarify.
I suppose you could use a PSD or AI to Sketch converter. I'm unsure about other file types.
I am not arguing that subscription models forced by Adobe on users is a good thing. It is, IMO, horrible and is the reason I am still using CS3 for my photography hobby.
Photoshop Illustrator and inDesign haven't had upgrade worthy releases since like CS5. Acrobat Pro seems to be getting worse.
This has allowed smaller software applications such as Sketch, The Affinity Suite and Capture One to grab marketshare. I think Sketch’s current business model is perfect. Customers pay for a year of updates. If a customer decides not to upgrade, they stay at the same version as when their license expires.
I’m certain Adobe has made a good amount of money in the short term, but they've forfeited a monopoly. I’m more skeptical about their long-term business.
