I agree. Currently , self hosting a service is somewhat difficult. It also requires some amount of technical knowledge. Some services can be installed just by entering one command - Nextcloud? While some other services are much more difficult to set up and get it running. Maintaining, updating and backing up is another story and is time consuming.

Also, not everyone can afford to pay money for hosting an instance.

I hope more services similar to mastohost will appear and become popular.
