Watching ollama pivot from a somewhat scrappy yet amazingly important and well designed open source project to a regular "for-profit company" is going to be sad. Thankfully, this may just leave more room for other open source local inference engines.
Their FOSS local inference service didn't go anywhere. This isn't Anaconda, they didn't do a bait and switch to screw their core users. It isn't sinful for devs to try and earn a living.
If you earn a living using something someone else built, and expect them not to earn a living, your paycheck has a limited lifetime.
“Someone” in this context could be a person, a team, or a corporate entity. Free may be temporary.
