I buy the support argument for companies.

I also buy the argument that a lot of time people are actually paying for cloud storage. While I'd love to see a generic protocol for cloud or self-hosted storage that every app can sync to, I expect we'll continue to see subscription software persist by locking down and gatekeeping cloud storage and sync, too.

But really I would be happy for that to go away.

I don't use much software that's sold in any way[0], and I'd prefer it to be none. The ideal situation is for it to always be better to collaborate on open source software than to build in private and keep it to yourself.

[0] I do donate to projects I like and use, though
