@janxyz I think this interview answers your question:
> There's practical reasons for adopting Open Source tooling, there's many, many practical reasons [ . . . ]> [ . . . ] if you could try Penpot, or if you could try Inkscape, it will make it easier to work with you in the Open Source context, and I'll give one example [ . . . ]
> [ . . . ] a particular upstream Open Source project that's pretty well known. They had engaged with some designers, and the designers used a ... unnamed, cloud-based design tool to give them a whole set of mockups and templates and stuff [ . . . ]
> [ . . . ] they didn't renew the subscription, so by the time I got to the project , I'm clicking through to all the mocks, they're gone [ . . . ]
> [ . . . ] that project was set back so far from a proprietary tool being introduced into the mix, so having files in open standard-based formats and in Open Source tooling means that project won't be left high and dry when you've moved on
