Open source not running locally is closed source, for all intents and purposes.

A GNU/Linux box supposedly loaded with nothing but software libre is closed source, if it's remote to you and you don't own it. If you send your data to it to be processed, who knows what happens to it.

I hear what you’re saying, and I agree that running something locally is appreciably different than using something hosted elsewhere.

But I think it’s critical to be precise about this. Open source is still open source, and this designation is still meaningful even if an open source product provides a hosted version. The downsides of letting someone else host something are independent of the the open/closed source status.
