It’s not that power users aren’t a market, it’s that casual users are now the larger market and cheaper to serve, and software companies have been catching on to that, to the detriment of power users.
But I definitely struggle with the comparison between power users and casual users. Like I wouldn't characterize designers that use Figma as casual users, it's that the needs of software designers have changed so much, and those changes mean treating design software more like office suite software make sense.
I guess the comparison of casual users and power users is more apt when comparing the Adobe suite and Affinity suite. And, e.g., Final Cut Pro X and CapCut are evidence of a wider industry trend towards serving that market. I wouldn't necessarily say that's to the detriment of power users though, it seems like there's software to serve both markets now?
So I don’t understand what properties of office suites you are alluding to here. Or is your point that the previously desktop-only software suites now have web-based counterparts, and the latter aren’t catering to power users anymore?
Yes this. More specifically collaborative software (e.g., with features like live-collaborative editing) tend to be less capable than non-collaborative software.
These are not 1-for-1 comparisons though (Figma vs. Canva), I didn't mean to imply they were. E.g., Canva isn't emphasizing collaboration. But office suite software does also have a lower barrier of entry than creative software, which I think Canva's strategy should probably capitalize on. E.g., the market has already been split for pro vs prosumer/casual, I think Canva strategy will probably be to emphasize this split short term, which would mean focusing on ease of use at the expense of complex features (and then consider the more technically complicated led shift to collaborative web-based versions later, leveraging what they've learned so far).
