And what do we get in return? A worse experience than cloud-based services.

I have to disagree somewhat, it’s a different experience that is absolutely more difficult in many ways, but for those of us who value privacy, control over our data, and don’t like ads, the trade-off is worth it. Also it goes without saying that the usability of selfhosted apps has exploded in the past few years and it will likely become less and less of an issue.
