Does the UK's online bill affect self-hosted chat? What about open standards?

The text has an exemption for internal systems run by businesses, but none for purely private ones (e.g. if you run a matrix server for friends and family).

The use of scanning on the user devices also seems to create a difficulty for open source and open standards, where the provider does not control the end device.
