I feel sketch fell out of favor as well. 12 years ago it was everywhere. I have seen it replaced by figma and very rarely mentioned nowadays. And I say it as a frontend dev who worked with different designers over the years.
I never worked in the US, but Sketch was huge in the two places I worked (Europe and Latin America), to the point companies that worked together with Microsoft (a couple shops I worked for) were purchasing Macs just to run it.
I bet those two places were swimming in money then, as Southern Europe and Latin America are not regions where most developers are swimming in money, US style.
To put this in perspective, in Portugal that would be about two months salary, assuming running expenses, where minimum wage is about 800 euros, and top jobs in IT pay around 1 500 euros after taxes.
Everyone that owns a Mac tends to buy them in on credit, or with bundles with their mobile/cable operator, which are anyway credits in disguise.
Never worked in Southern Europe. In Germany, everyone had Macs in the companies I worked.
In Latin America... The last Mac I bought there was about half of my IT salary there, but that was 2012, a couple years before I left. So it was ok for companies to purchase them. Today? Probably not... I don't even know anyone who's still there and working for local companies.
I've liked Icons8's Lunacy as a free alternative to Sketch and Figma. It works with Sketch files and Figma projects, and isn't Mac-exclusive or a website like Figma.
