You won't be switching from Sketch to Figma in 2025.
If anything, it'll be the other way around.
For starters, when it comes to price and features (flex layout coming soon) it doesn't make sense.
But you also CAN'T do it:
The .sketch file importer in Figma completely garbles the files and makes them unusable.
What was once the main thing leading people to switch, combined with bad pricing, bad policies, bad privacy and forced features seems to be another nail in the coffin.
Importing a .fig file into Sketch actually works way better.
Seems like this will be the way.
